Sadly, this is probably the authoritative answer I was hoping not to

a bit to make this happen with a special tool (perhaps offline for a bit
- you'd only have to manage something less than a single MB of data) but
I'm guessing nobody has felt the itch to make such a tool.

As I originally stated, I've done this successfully many times with a
command like:
mount -t ext{2,3,4} /dev/sdXY /media/temp -o rw
But if you write to it, can you clobber the raid superblock? That is,
is it somehow allocated as used space in the filesystem or is there a
difference it the space available on the md and direct partition, or
something else?

However, we like to believe that it is actually simpler to understand systemd than a Shell-based boot for most people. Surprised we say that? Well, as it turns out, Shell is not a pretty language to learn, it's syntax is arcane and complex. systemd unit files are substantially easier to understand, they do not expose a programming language, but are simple and declarative by nature. That all said, if you are experienced in shell, then yes, adopting systemd will take a bit of learning. I think the point is that systemd unit file syntax is significantly simpler than shell syntax -- can we agree on that? No. Everything you type on a command line is shell syntax. If you don't think that is an appropriate way to start programs you probably shouldn't be using a unix-like system, much less redesigning it. If you don't think the shell is the best tool, how about fixing it so it will be the best in all situations. It also is significantly less-featureful than a shell programming language. Yes, you're going to be using shell elsewhere, but in my experience, the structure of most SysVinit scripts is nearly identical, and where it deviates is where things often get confusing to people not as familiar with shell scripting.

You could, if every command typed by every user since unix v7 had been parsed with C syntax instead of shell so there would be something they could 'stick to'. But, that's not true. Every *real* user of UNIX-like systems should be capable of writing C code, which is used in so many more circumstances than bash. That might be true, but it is irrelevant. Why would you ever want to start your system using some clunky shell-based interpreter like bash, (which cannot even share memory between processes in a native way), when you can simply write a short piece of C code, fork() all your services, compile it, and run? If you think bash is 'clunky', then why even run an operating system where it is used as the native user interface?Or, if you need to change something, why not fix bash to have the close mapping to system calls that bourne shell had back in the days before sockets? And if you really insist on writing commands interactively into a command prompt, you are welcome to use tcsh, and reuse all the syntax and well-earned knowledge of C, rather than invest time to learn yet-another-obscure-scripting-language... Right? Or not? Well, Bill Joy thought so. I wouldn't argue with him about it for his own use, but for everyone else it is just another incompatible waste of human time. If not, you may want to reconsider your argument against systemd --- it's simple, clean, declarative, does one thing and does it well, and it doesn't pretend to be a panacea of system administration like bash does. I'm sure it can work - and will. But I'm equally sure that in my lifetime the cheap computer time it might save for me in infrequent server reboots will never be a win over the expensive human time for the staff training and new documentation that will be needed to deal with it and the differences in the different systems that will be running concurrently for a long time.

I think you and I remember a different set of lists. I remember lots of
griping about changes being forced down throats. Heh, a quick perusal
of one of the lists' archives just a minute ago confirmed my recollection.
No, that is exactly my point. Back then the griping by affected
active users happened in more or less real time compared to the
changes being done. Now fedora goes off on its own merry way for
years before its breakage comes back to haunt the people that wanted
stability.
With the latter approach, there was a much better sense of the cost of
breaking things that previously worked.
Do you remember the brouhaha over libc5 that 'just worked' versus the
'changed for no reason' glibc2? And don't get me started on the
recollections over the GNOME 1 to 2 upgrade (or fvwm to GNOME, for that
matter!), or the various KDE upgrades (and the entire lack of KDE for
RHL 5.x due to the odd license for Qt, remember?
Don't think people running a bunch of RH5 servers really cared about X
or desktops at all...
And then
all the i18n changes for 8.0 (I dealt with that one directly, since the
PostgreSQL ANSI C default had to be changed to whatever was now
localized
That one was sort of inevitable. Likewise for grub2 and UEFI...
The bad rep for x.0 releases
started somewhere, remember?
Well, that was the equivalent of fedora. You don't use that in
production. The x.2 release mapped pretty well to 'enterprise'' -
except maybe for 8.x and 9 which never really were very good.
Not that I necessarily disagree with your observations, by the way. I'm
just looking at the brushstrokes of the really big picture and
remembering how at the time it seemed like we sometimes were just moving
from one kluge to another (if you insist on the alternate spelling
'kludge' feel free to use it.). But it was a blast being there and
watching this thing called Linux find its wings, no?
In these observations you have to take into account just how badly
broken the base code was back then. Wade through some old changelogs
if you disagree. There were real reasons that things had to change.
But by, say, CentOS5 or so we had systems that would run indefinitely
we a few security updates now and then. (Actually CentOS3 was pretty
solid, but you have to follow the kernel).
And I have two previous versions of CentOS to fall back on while I learn
the new tools; I have both C5 and C6 in production, and have plenty of
time in which to do a proper analysis on the best way ('best way' of
course being subjective; there is no such thing as an entirely objective
'best way') for me to leverage the new tools. The fact of the matter is
that Red Hat would not bet the farm on systemd without substantial
buy-in from a large number of people. The further fact the Debian and
others have come to the same conclusion speaks volumes, whether any
given person thinks it stupid or not. And I don't have enough data to
know whether it's going to work for me or not; I'm definitely not going
to knee-jerk about it, though.
I'm never against adding new options and features. But I am very
aware of the cost of not making the new version backwards compatible
with anything the old version would have handled. And I'm rarely
convinced that someone who doesn't consider backwards compatibility as
a first priority is going to do so later either, so you are likely
wasting your time learning to work with today's version since
tomorrows will break what you just did.
But the rumors of something 'killing' Linux have and will always be
exaggerated. Systemd certainly isn't going to, if gcc 2.96 didn't. I
mean, think about it: the first rev out of gcc 2.96 wouldn't even
compile the Linux kernel, IIRC!
Yes, but on the other hand, people still pay large sums of money for
other operating systems. And there are some reasons for that.

It's sort of the same as asking that about getting a shiny new car with a different door size that won't carry your old stuff without changes and then still won't do it any better. Our services take all the hardware can do and a lot of startup initialization on their own. Saving a fraction of a second of system time starting them is never going to be a good tradeoff for needing additional engineer training time on how to port them between two different versions of the same OS. If there is no ROI, or a really long ROI, well, I still have C6 to run until 2020 while I invest the time in determining if a new way is better or not. So a deferred cost doesn't matter to you? You aren't young enough to still think that 6 years is a long time away, are you? Fact is that all of the major Linux distributions are going this way; do you really think all of them would change if this change were stupid? Yes, Linux distributions do a lot of things I consider stupid. Take the difficulty of maintaining real video drivers as an example. Even the Unix philosophy was new at one point. Just because it works doesn't mean it's the best that can be found. Re-using things that work may not be best, but if everyone is continually forced to re-implement them, they will never get a chance to do what is best. In terms of your ROI question, you should be asking if that is the best use of your time. Even if the changes themselves are minor, you have to cover the cost of paying some number of people for that 'get used to the syntax' step. Personally I think Red Hat did everyone a disservice by splitting the development side off to fedora and divorcing it from the enterprise users that like the consistency. Consistency is not the only goal. But that's why we are here using an 'enterprise' release, not rebuilding gentoo every day. Efficiency should trump consistency, Efficiency comes from following standards so components are reusable and can be layered on top of each other. Then you can focus on making the least efficient part better and spend your time where it will make a difference. Adding options to increase efficiency is great - as long as you don't break backwards compatibility. and I for one like being able to see where the direction lies well in advance of EL adopting a feature blind. Or don't you remember how Red Hat Linux development used to be before Fedora and the openness of that process? Yes, I remember it worked fantastically well up through at least RH7 - which was pretty much compatible with CentOS3. That was back when people actually using the systems contributed their fixes directly. I had a couple of 4+ year uptime runs on a system with RH7 + updates - and only shut it down to move it once. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

(I know; I have an older SuperMicro server here that passes memory testing in POST but throws nearly continuous ECC errors in operation; it does operate, though). If it fails during spinup, flag the failure while spinning up another server. I don't think that is generally true. I've seen several IBM systems disable memory during POST and come up running will a smaller amount. Virtual servers have no need of POST (they also don't save as much power; although dynamic load balancing can do some predictive heuristics and spin up host hypervisors as needed and do live migration of server processes dynamically). Our services that need scaling need all of the hardware capability and aren't virtualized. That might change someday... To detect failures early, spin up every server in a rotating sequence with a testing instance, and skip POST entirely. If you have to, spin up the server in a stateless mode and put it to sleep. Then wake it up with dynamic state. Our servers tend to just run till they die. If we didn't need them we wouldn't have bought them in the first place. I suppose there are businesses with different processes that come and go, but I'm not sure that is desirable. Long POSTs need to go away, with better fault tolerance after spinup being far more desirable, much like the promise of the old as dirt Tandem NonStop system.

I don't think PG + WAL provides this type of capability. I think it does. You should be able to have a base dump plus some number of incremental logs that you can apply to get to a point in time. Might take longer than loading a single dump, though. Depending on your data, you might be able to export it as tables in sorted order for snapshots that would diff nicely, but it is painful to develop things that break with changes in the data schema.

one) ip address. I’ve setup scripts (for os x, w7) to collect these data and
push it into a db. Periodically, the /etc/hosts file on the backuppc server
is updated with these data.
Now, nmblookup doesn’t use the /etc/hosts file, but $Conf{ClientNameAlias} =
‘xxx.xxx.xxx.xxx’ in the /etc/backuppc/CLIENTS.pl file which can be updated
periodically as well to the latest data.
Are there other/simpler possibilities already implemented for clients to be
able to backup from “foreign” networks? Is there any possibility to deal
with the multiple ip addresses a client can have?
If the client pc users logs into the web interface to start the
backup, it will find the address. But usually the bigger problem is
that these roaming connections are going through a NAT router or
firewall so the server can't connect back anyway. One solution is to
run a VPN service like openvpn on the client and server and configure
it to assign a known private address to each client when it is
connected - and configure backuppc to use that address (via
ClientAliasName).

The rsync process at the client side does nothing (no CPU nor mem activity). It is idle (blocked).

I don't know... The backuppc-internal rsync can't handle any extraneous messages before the remote rsync handshake. That is a known problem but usually triggered by a login message from the remote side. I thought it would exit quickly with that error, but maybe it waits for ssh to exit. In any case you'll have to find a way to get that message out of the data stream. Meanwhile you might try setting up rsync in daemon mode on the remote side and using the rsyncd xfer method. That would get ssh out of the picture. -- Les Mikesell lesmikes...@gmail.com -- Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

In our situation, we're writing pg_dump files repeatedly, each file being highly similar to the previous file.

Assume that we're writing a 500 MB file with only 100 KB of changes. Other than a utility like diff, is there a file system that would only write 100KB and not 500 MB of data? In concept, this would work similarly to using the 'diff' utility... There is something called rdiff-backup (http://www.nongnu.org/rdiff-backup/ and packaged in EPEL) that does reverse diffs at the application level.

[CentOS] gdb question
If you are trying to debug a core dump from a different machine, how do you tell gdb where to look for the debug info files to match the shared libs that you have in a non-standard location? It finds the shared libs themselves with a 'set solib-absolute-path' directive, but it doesn't look for the corresponding (relative) usr/lib/debug/... file that you get if you extract the debuginfo rpm in the same place. And if I set debug-file-directory to the top of the tree, it wants to also add the solib-absolute-path to that. Is there some way to make it realize that the top of the tree is the same for both? -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Is this running some implementation of busybox as a shell and combination of what would normally be independent commands? Even then it doesn't make a lot of sense that it would involve your non-stock OptWare client which would be the part that doesn't understand the stock smb.conf contents.

Building an incorrect view can't be the cause, because then the file would simply be transfered (and logged as pool instead of same). Maybe we should think more closely about the rsync on the *remote end*, the host to be backed up. I'm not quite sure which side (of rsync) is responsible for doing the file list comparison, and I haven't really got the time to look right now, but failing to detect/signal unchanged files would result in exactly what you see. I think what should be happening is that the remote side sends the equivalent of a full directory tree listing, then both the backuppc server and the remote walk the list comparing the contents with block checksums. In the case of fulls every file should be checked and files that are the same should be logged as 'same' and linked into the new backup tree. This behavior doesn't make sense at all, but I don't see how the remote side could miss sending the directory listing for the files in the last backup, and then the server side should log them as 'same', 'create', or 'pool'. -- Les Mikesell lesmikes...@gmail.com -- Open source business process management suite built on Java and Eclipse Turn processes into business applications with Bonita BPM Community Edition Quickly connect people, data, and systems into organized workflows Winner of BOSSIE, CODIE, OW2 and Gartner awards http://p.sf.net/sfu/Bonitasoft ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

QNAP customizes some daemon (like Samba) adding new non-samba conf parameters, so the optware smbclient utilized by backuppc return warnings like ignoring unknown parameter 'conn log'. QNAP does not install a smbclient, so I must use the optware version that does not understand the customized QNAP parameters. That warning message cause backups to fail, even it is only a warning and even with rsync backups (samba should not be used). Smbclient will default to reading smb.conf from the standard location, but you could override that by adding '-s /path/to/your/smb.conf' to the SmbClient related commands. I attach BackupPC_Dump -i -v output. On the CGI console I see the backup jobs (all rsync based) in running (but idle) state for several hours before a timeout interrupts them. This appear like a backuppc bug because: - a warning message cause backup to fail - a samba configuration problem cause rsync based backups to hang and fail. I'm missing something here.

I did do some tests with a back-rev plugin and having a pick-list of projects from the server was nice, but it seemed confusing as to how the plugin options actually mapped to what it would do with cov-build, etc. -- Les Mikesell lesmikes...@gmail.com -- You received this message because you are subscribed to the Google Groups Jenkins Users group.

I've only seen it touted for machines with enormous disks, 200TB plus. It is generally better at handling a lot of files - faster creation/deletion when there are a large number in the same directory. I'm wondering if, for the home user, BackupPC would be a good test of that? Otherwise I can't think of a case where I would have a very large number of files in the same directory. There are users on the backuppc list that recommend XFS - but for 'home' size systems it probably doesn't matter that much. The only down side for a long time has been on 32bit machines where the RH default 4k kernel stacks were too small. Do you mean that that is a down side of XFS, or ext4? XFS - it needs more working space.. RedHat's choice to configure the kernel for 4k stacks on 32bit systems is probably the reason XFS wasn't the default filesystem in earlier versions. And now that I think of it, this may be an issue again if CentOS revives 32bit support. Does XFS have the same problems that LVM has if there are disk faults? You can't really expect any file system to work if the disk underneath is bad. Raid is your friend there. In my meagre experience, when a disk shows signs of going bad I have been able to copy most of ext3/ext4 disks before compete failure, while LVM disks have been beyond (my) rescue. Actually, this was in the time of SCSI disks, which seemed quite good at giving advance warning of failure. I'm not sure what controls the number of soft retries before giving up at the hardware layer. My only experience is that with RAID1 pairs a mirror drive seems to get kicked out at the first hint of an error but the last remaining drive will try much harder before giving up. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] yum install to a portable location
On Wed, Jun 11, 2014 at 11:26 AM, Dan Hyatt dhy...@dsgmail.wustl.edu wrote: I have googled, read the man page, and such. What I am trying to do is install applications to a NFS mounted drive, where the libraries and everything are locally installed on that filesystem so that it is portable across servers (I have over 100 servers which each need specific applications installed via yum and we do not want to install 100 copies). We tried the yum relocate and it was not available on Centos6.4 and yum --nogpgcheck localinstall R-3.1.0-5.el6.x86_64 I want the binaries and all dependencies in the application filesystem which is remote mounted on all servers. I don't think there is a generic way of doing this since yum can pretty much install anything anywhere and run the postinstall scripts that might only work on the host where it runs. However, for typical things it might work to install everything on one host where / is exported and mounted somewhere on the other systems with PATH and LD_LIBRARY_PATH tweaked to visit the bin,sbin,usr/sbin,usr/bin and equivalent library paths on the mountpoint after the local locations. Things like perl modules will probably become a horrible mess, though, and other things might need a splattering of symlinks to work. Might be easier to PXE boot into an NFS-mounted root with DRBL or the like if you need to save disk space. On the other hand, it's really not that hard to tell yum on 100 machines to install the package. -- Les Mikesell lesmikes...@gmail.com ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] Google chrome vs network settings proxy?
I started using chrome on the RHEL7 beta after some firefox hangs - but maybe this behavior is generic. I have the system 'network settings/network proxy' set to use squid on another host for connections out of the private range we use. This proxy requires authentication so I can always tell the first time a browser uses it. However, I can start a chrome connection to gmail and it just goes direct (which happens to work, I just prefer the proxy which will use a different outbound route). If I go to any non-google site, it uses the proxy and will pop up the expected authentication dialog on the first connection.
