Potential differences:

bareos instead of bacula

my version is 5 (bacula 7 is current; I'm not certain if it has usable Win
client though - didn't check lately).

If I were to speculate I would say that what you see may come from "too
much work" done on client side, like packing whole directories ("folders"
as I should have used MS windows language), and sending the whole thing to
backup server, but I most likely will be wrong about that as: the stuff
that walks you trough directory tree comes from database, which is filled
I bet by director (receiving infor. from fd), no matter that files are
being sent by fd to sd. Anyway, I would try to remove compression wherever
it is configured and see if that makes any difference.

But you probably need bareos _expert_, not just bacula _user_ to find the
solution.

Incidentally, what happens if you request to restore all ("add all" will
be the only command you need, then say "done").

Good luck!

My case may be irrelevant as what I have is: server: FreeBSD 9.3, bacula
5, still here is what I have on the server side for Windows 7 client:

bconsole

restore

5

[here I chose the client]
...

You are now entering file selection mode where you add (mark) and
remove (unmark) files to be restored. No files are initially added, unless
you used the "all" keyword on the command line.
Enter "done" to leave this mode.

cwd is: /

cd C:/Users/[username]/Documents

dir

...
C:/Users/[username]/Documents/Visual Studio 2005/
...

dir "Visual Studio 2005"
drwxrwxrwx   1 root wheel  0  2015-06-03 11:55:12 
C:/Users/[username]/Documents/Visual Studio 2005/

[looks like it doesn't like to show the content, but if I enter there,
I'll see stuff there, so now I just will add it to restore]

add "Visual Studio 2005"
4 files marked.

done

...

7 files selected to be restored.

...

So, in my case the files are there. What happens it you use "add" command
to add directory containing the fires you need to restore?

Thanks.

Re: [CentOS] Google Ads in rsyslog documentation files

[Peter Eckel]

Hi Mark, 

I'm not sure whether upstream is the right place to address this, but I'll try. 
I just downloaded all versions of the rsyslog sources from rsyslog.com, and 
found 'googlesyndication' links in the following versions: 

rsyslog-4.8.0
rsyslog-5.10.0
rsyslog-5.10.1
rsyslog-5.8.13
rsyslog-6.6.0
rsyslog-7.3.0
rsyslog-7.3.1
rsyslog-7.3.2
rsyslog-7.3.3
rsyslog-7.3.4
rsyslog-7.3.5
rsyslog-7.3.6
rsyslog-7.3.7
rsyslog-7.3.8
rsyslog-7.3.9
rsyslog-7.3.10
rsyslog-7.3.11
rsyslog-7.3.12
rsyslog-7.4.0
rsyslog-7.4.1
rsyslog-7.4.2
rsyslog-7.4.3
rsyslog-7.4.4
rsyslog-7.4.5
rsyslog-7.4.6
rsyslog-7.4.7
rsyslog-7.4.8
rsyslog-7.4.9
rsyslog-7.4.10
rsyslog-7.5.0
rsyslog-7.5.1
rsyslog-7.5.2
rsyslog-7.5.3
rsyslog-7.5.4
rsyslog-7.5.5
rsyslog-7.5.6

Which means it's gone in 8.x.x and in 7.x.x starting from 7.5.6. 4.x.x, 5.x.x 
and 6.x.x haven't been cleaned ever.

CASE 01544649 opened upstream.

Cheers,

I cannot do that until I either mark or (thanks for telling me about

And it's still the same - it does not show the two textfiles in the

I've been building C7 VMs with RAID-1 in Virtualbox these last couple
of days, to pin down exactly how to do it. based on the link above,
but I'm making "real" partitions instead of LVM.

The current iteration seems to be running fine, but I had an odd problem
when configuring the partitions: for two 10 gig virtual drives, it wouldn't
let me use the last gig of space. or maybe it has some other issue on the
max partition size,... it seemed to max out at around 9900 MB. This for
sure won't do when I build it on real hardware, so I'm wondering if
anyone else here has a clue what's going on??

thanks in advance!

[CentOS] Glibc vulnerbality CVE-2015-1781

[Venkateswara Rao Dokku]

Hi,

We are using CentOS 5.5 as a base OS for one of our products.The version of
Glibc we are using was glibc-2.5-123.el5_11.1.

We wanted to see whether this glibc is vulerable to CVE-2015-1781. I have
gone through re-documentation & came across the following link
https://access.redhat.com/security/cve/cve-2015-1781

In the link it is mentioned that, the CVE will not be fixed in Red-Hat 5
version. What does that mean? I mean, whether the RedHat 5 is vulnerable &
fix is not available or RedHat 5 is not vulnerable, hence the fix is not
given?

Thanks for the info.

Read what it says a little higher on that webpage, under the Statement heading:

Red Hat Enterprise Linux 5 is now in Production 3 Phase of the support and

IIRC, Anaconda can't create "raid1" LVM volumes.  That is, you can't 
create LVs that are mirrored across multiple PVs.  You can create md 
RAID1 volumes and make a PV of the resulting RAID volume, though.


So I think what you're probably doing is creating 100MB /boot partition, 
and then two md RAID component partitions of 9900MB.

Re: [CentOS] IP table Restore

It would seem there's some kind of invalid configuration on line 2 of

You'd have to post at least the first few lines of said file to learn more 
about what's actually causing it.

If I recall correctly, you are using CentOS 7?   With 7, you really 
should be using firewalld rather than manually writing iptables rules. 
see the firewall section of the RHEL 7 networking manual I previously 
linked, twice.


otherwise, which part of that error is unclear?   check line 2 of 
/etc/sysconfig/iptables, it has a syntax error.   there may be more 
information in the system logs, see chapter 20, 'logging'

"obnoxious" would be the word I would use. I checked on one of my CentOS 6
boxes, and it is there. I never had high opinion about google itself, but
today RedHat fell in my eyes one notch down as well.

"Disconcerting" isn't the word I would use. Completely unacceptable is
what I'd say. I think it's time to put in a bug report to upstream I

That's a configuration for a Linux system running Debian or Ubuntu 
Linux. CentOS (the topic of this mailing list) and other distributions 
in the Red Hat family use a completely different syntax for network

If you're completely new to Linux, I'd suggest you find a local Linux

[CentOS] LVM - how to change lv from linear to stripped? Is it possible?

[Rafał Radecki]

Hi All.

Currently I am trying to change a logical volume from linear to stripped
because I would like to have a better write throughput. I would like to
perform this change "live" without stopping access to this lv.

I have found two interesting examples:
http://community.hpe.com/t5/System-Administration/Need-to-move-the-data-from-Linear-LV-to-stripped-LV-on-RHEL-5-7/td-p/6134323
http://www.depesz.com/2015/10/08/converting-logical-volume-so-that-its-striped/
Both say basically to:
- change the lv to a mirrored one by adding a stripped copy (~second device
in RAID1)
- change it back to a non-mirrored one by removing the primary linear lv
(~first, source device in RAID1)

My os is:
$ cat /etc/redhat-release
CentOS Linux release 7.1.1503 (Core)
$ uname -r
3.10.0-229.14.1.el7.x86_64
$ rpm -qa | grep -i lvm
lvm2-libs-2.02.115-3.el7_1.1.x86_64
lvm2-2.02.115-3.el7_1.1.x86_64

And the solution proposed in above examples does not work on it.
After (lv xxx is only on /dev/sdb4 before):
# lvconvert --mirrors 1 --stripes 4  /dev/cinder-volumes/xxx /dev/sda4
/dev/sdc4 /dev/sdd4 /dev/sdf4
I am getting in "lvdisplay -m":

--- Logical volume ---

And in "pvdisplay -m":

  Physical extent 1 to 16386:
Logical volume  /dev/cinder-volumes/xxx_rimage_0
Logical extents 0 to 16385
  Physical extent 16387 to 715254:
FREE

So the migration to a RAID1 logical volume is successful but the stripping
(above "lvconvert --mirrors 1 --stripes 4  /dev/cinder-volumes/xxx
/dev/sda4 /dev/sdc4 /dev/sdd4 /dev/sdf4") is not taken into consideration
because only /dev/sda4 and /dev/sdb4 are used for xxx logical volume
afterwards.

Also when I run:

# lvconvert -m 0 /dev/cinder-volumes/xxx /dev/sdb4

afterwards I get xxx logical volume only on /dev/sda4 and it is linear (not
stripped).

Can someone help me with this? ;)

Rafal.

Hint -- try the:

  systemctl list-units | grep ...

concept that you used previously and see what output you get.
[sub-hint -- the *nix world is case sensitive.]

This is a user (understanding) issue -- why are you including the
"-devel" list? Don't.

It seems that after updating the host to 6.7 some things have changed
that I didn't test.  Now the install continues, but just after switching
to graphical mode, it eats CPU time and doesn't proceed.  It once
reacted to CTRL-ALT keys (via the VNC menu) and I saw something like
"EQ overflow", but the next time it doesnt.

Anyway, I'll do some more testing, also with text mode, as I'm not
having a clear overview myself anymore on what's happening ;-).

Me too.

Well then, you need to figure out what you did differently in
setting up these two environments. This is something specific to
your process and procedures (or hardware/environment). There's not
much that we can help you with as you haven't provided any details.

[CentOS] LVM - stripped logical volumes by default?

[Rafał Radecki]

Hi All.

I am currently using OpenStack Juno on CentOS 7. The problem is that by
default OpenStack's Cinder service creates logical volumes of "linear"
type. I would like to have them stripped over all physical disks to get
better write performance.

Is there a way to tell LVM to create by default stripped volumes instead of
linear ones?

BR,
Rafal.
