Avago used to be HP's semiconductor business, was spun off in the great split/merger with Compaq as part of Aglient, then in 2005 kicked to the curb as an independent. They are big on analog, mixed signal, and microwave semiconductors. LSI had acquired 3Ware, ONStor, a bunch more, and merged them into Engenio, which was their NAS/SAN division, making OEM storage arrays sold by IBM, HP, Dell and others. Engenio has been sold to Network Appliance, the original NAS company. LSI acquired the Sandforce SSD chip business. Avago acquired and merged with LSI. Avago unbundled Sandforce and sold it to Seagate. Avago sold LSI's networking stuff to Intel just last week. AFAIK, Avago still sells the LSI sas chips and both megaraid and 3ware raid controllers. -- john r pierce 37N 122W somewhere on the middle of the left coast ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

I didn't know LSI sold them to someone else, www.3ware.com still redirects to LSI. To the credit of all 3ware owners, they left nicely working 3ware (engineering, manufacturing, etc) mechanism as is without destroying it. Which is rare, and they deserve my respect for that alone. I do like LSI too, and have a few of their megaraid controllers on long lived and still very reliable boxes.

I never heard about any LSI card called RAID which are not hardware RAID. I can not say the same about, say, Adaptec or HighPoint to name two. Some of Adaptec and some of HighPoint cards even though they are sold as "RAID" cards are junk and have no place in our server room. Areca, probably, is one more company whose RAID cards all are indeed hardware RAID cards (I have 3 or 4 Areca cards in our server room).

The LSI MegaRAID cards are real hardware RAID. What I have heard, but only validated the former, is that the 3ware UI is simpler but the MegaRAID controllers are faster.

If the drive that is member of hardware RAID failed (say timed out while dealing with reallocation of badblock), it is kicked out of the RAID, I get notification by 3ware daemon, hot unplug the drive, hot plug in replacement (of same or larger size), and start rebuild RAID through firmware utility, or GUI interface, or controller starts RAID rebuild automatically if configured so. The system on the machine has no idea about all this and keeps running happily. I do no forensics on failed drives. I run manufacturer drive fitness test (whichever it is called by particular manufacturer), if drive passes, I usually reuse it, if it fails test, I send it to drive manufacturer for warranty replacement or toss if it is out of warranty. > > The formatting of disks on HW RAID is transparent to Linux. > Therefore my disks are all RAID or not. > > What if I wanted to mix and match? With 3ware RAID controller you can export one or more of attached drives directly to the system. They can not participate in [hardware] RAID then. > Maybe I don't want my swap > RAID for performance. Speaking of swap: RAM is large and cheap these days. I do not use swap on machines with 32 GB of RAM or larger. On multitasking system you have to switch between processes, which is more often than every millisecond. Imagine now you need to swap in or out 32GB during some of the switching between processes. Your system will be on its knees just because of that. Unless you have very special block device which is almost as fast as RAM, which you better just have added to the address space of RAM (from kernel point of view), so we are not speaking of these devices as of hard drives. > > The idea of taking my data (which is controlled by an OSS > Operating System, Linux) and putting it behind a closed source > and closed system RAID controller is appalling to me. Me too. Yet all of us use them. Example: hard drive firmware. Which has a bit more sophisticated function than just take data and write track or other way around. It detects badblocks, reallocated them, recovers as much as possible information that was inside that bad block. Another example: video card, say, NVIDIA one. It has processors inside that run software that is flashed on its non-volatile memory. Now, with Nvidia cards sometimes you have to use proprietary driver (if you have more or less sophisticated display arrangement). Which is closed code binary driver. What you compile when you install that is just an interface between closed code driver and this particular version of kernel. And this code runs not in the card itself, but under your system. And the list goes on. Not to mention our cell phones... The only time I was mad about firmware of some controller was one particular version of via PATA controller that had a bug which was leading to drive corruption... > > It comes down to this: Linux knows where and when to position > the heads of disks in order to max performance. If a > RAID controller is in the middle, whatever algorithm > Linux is using is no longer valid. The RAID controller > is the one who makes the I/O decisions. Yes, but... And some of what I'll say was already mentioned in this thread. You can tweak RAID controller to align stripe sizes with optimal data chunks of the drives. Furthermore, you can have cache (battery backed up), which increases device speed tremendously (30 times I saw for something particular - just off the top of my head). Of course, RAM is used as a cache for software RAID, but to the contrary to RAID controller cache RAM content vanishes with power loss. You don't seem to be the person who had to recover after [software] RAID cache loss. And _I_ definitely will not like to be the one. Hence I use hardware RAID, with optimized stripe size, and optimized filesystem block size, and with cache in RAID controller that is battery backed up. If you beat me in IO with software RAID, I will live with that. As I do not like to give up reliability. Not at as small extra cost as I have to pay for hardware RAID. (And I do not include into hardware RAID these fake "raid" cards that rely on "driver" - which are indeed software RAID cards. 3ware never fell that low to make/sell any of such junk. Somebody who knows LSI better than I do will probably say the same about them). Again, just my 2c.

Re: [CentOS] HP ProLiant DL380 G5
Valeri, I hope you realize that your arguments for hardware RAID all depend on everything working just right. If something goes wrong with a disk (on HW RAID) you can't just simply take out the disk, move it to another computer and maybe do some forensics. The formatting of disks on HW RAID is transparent to Linux. Therefore my disks are all RAID or not. What if I wanted to mix and match? Maybe I don't want my swap RAID for performance. The idea of taking my data (which is controlled by an OSS Operating System, Linux) and putting it behind a closed source and closed system RAID controller is appalling to me. It comes down to this: Linux knows where and when to position the heads of disks in order to max performance. If a RAID controller is in the middle, whatever algorithm Linux is using is no longer valid. The RAID controller is the one who makes the I/O decisions. Sorry, this is not something I want to live with.

mmap_zero is a fairly dangerous access. It means the object is
attempting to memeory map
low memory in the kernel. Bugs in the kernel have been known to allow
priv escallation, can be prevented by this check.
http://eparis.livejournal.com/
Talks about the access check.
I usually tell people to avoid these apps, but if you need to run it,
you can turn the protection off as the alert told you.

Re: [CentOS] HP ProLiant DL380 G5
You know that hpacucli (and MegaCli on LSI-based hardware RAID systems) can usually tell you more about the array and the drives than mdadm can, right? Also, if you're doing parity, having hardware RAID moves the parity calculations to a dedicated ASIC, avoiding any load of note on the CPU. Also, with hardware RAID, you get battery-backed or flash-backed write-back caching, which can dramatically improve performance. That said, mdadm is better that cheap fake-RAID controllers like you find on most mainboards, I will give you that. digimer On 21/08/14 04:33 PM, GKH wrote: > Hate to change the conversation here but that's why I hate hardware RAID. > If it was software RAID, Linux would always tell you what's going on. > Besides, Linux knows much more about what is going on on the disk and what is > about to happen (like a megabyte DMA transfer). > > BTW, check if something is creating: > > /forcefsck > > That would make the fsck run every time. > > GKH > >> Matt wrote: >>> I have CentOS 6.x installed on a "HP ProLiant DL380 G5" server.

Re: [CentOS] HP ProLiant DL380 G5
Hate to change the conversation here but that's why I hate hardware RAID. If it was software RAID, Linux would always tell you what's going on. Besides, Linux knows much more about what is going on on the disk and what is about to happen (like a megabyte DMA transfer). BTW, check if something is creating: /forcefsck That would make the fsck run every time. GKH > Matt wrote: >> I have CentOS 6.x installed on a "HP ProLiant DL380 G5" server.

[CentOS] SOLVED!! - Re: Trying to override MAC addr
Deleted all the back-and-forthing and will only include what finally
worked. Sheesh, I got buried in the cruft on this one.
Edit /etc/udev/rules.d/70-persistent-net.rules to have your REAL mac addr:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:c3:04:01:77:c3", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
Edit /etc/sysconfig/network-scripts/ifcfg-eth0 with the mac addr you want:
MACADDR=02:67:15:00:01:79
REBOOT!
running start_udev at this point only added the eth1 entry again. The
kernel was so confused that I needed to 'clean house'.
# ifconfig
eth0 Link encap:Ethernet HWaddr 02:67:15:00:01:79
inet addr:208.83.67.179 Bcast:208.83.67.255 Mask:255.255.255.0

RX bytes:16489 (16.1 KiB) TX bytes:6313 (6.1 KiB)
Interrupt:87 Base address:0x6000
I got my desired MAC addr, my static IPv4 addr, and IPv6 RA + MAC =
desired IPv6 addr.
Now to reveal why I went to these efforts. STATIC IPv6 is badness when
you want to be able to change prefixes but have 'nice' IPv6 addresses.
So I studied how IPv6 suffixes are currently constructed, decided what I
wanted, and off to the races.
Well another reason, is I will be working in IEEE 802 MAC privacy Study
Group, and wanted to see what COULD be done to create privacy-enhancing
MAC addresses.
But thank you ALL for your efforts!

pretty sure you need to use NIC model specific utilities to do this,
ifcfg-ethN won't do it. the hwaddr= in there is for finding the nic,

just look at the file
in the past and on CentOS before RHEL7 it was to assign MAC/device-names
at boot, on recent Redhat based systems just remove it and stick with
place both in the ifcfg-files while disable biosdevname and systemd
devicenames at boot
both, that udev rules and what i explained you may collide or at least

I know with Arduinos (at least earlier network shields), there was no
MAC address assigned, either. So there, I had to assign it in the
compiled sketch.
I would expect there to be some program somewhere for the NIC to allow
you to program the static MAC.
I suppose 'ifconfig -a' doesn't show anything?

Re: [CentOS] Trying to override MAC addr
Robert, Sorry Dude. I did not mean to make things worse. All I wanted to say is this: It can be done via the ifconfig command. Now, # systemctl status network.service Tells me that network services still depend on: "ExecStart=/etc/rc.d/init.d/network start" Good! File: "/etc/sysconfig/network-scripts/ifup-eth" Says: "39 # bail out, if the MAC does not fit" Ok, perfect. As you already guessed we need to make this change early on. However, if all else fails, you can always source a custom script here and problem solved. I know, this is not elegant. But as an SA who sometimes needs to do dirty deeds... Again, apologies if I am being too simplistic/stupid here.

So that means I need to find the full syntax of this rule.
Oh, and there is no real MAC address and that MIGHT be part of the
problem. Many armv7 cards do not have eeprom so no MAC address. In
this case the kernel is creating the MAC address as local scope based on
the SID. So somewhere this is happening, and Hans (who maintains the
uboot Allwinner code) has not told me the magic goo; I have not seen any
posts from him so he may still be on Holidays.
But I will delve into udev syntax to see what I need to change the mac addr.

Note that you still have to tell the OS "See this real MAC address?
Change it to this new MAC address". Shy of reprogramming the NIC
directly, you will almost certainly need to continue to reference the
real MAC address.

Note that you generally need to stop the network, edit the udev file and
then restart the network. It will confuse the kernel otherwise.
Please also note that I've always moved names associated to devices,
I've not tried changing the address, so there might be something missing
there.

I worked a bit on this. I no longer have the MAC or HW addrs in
ifcfg-eth0. Only in /etc/udev/rules.d/70-persistent-net.rules, and only
for name=eth0:
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:67:15:00:01:79", ATTR{type}=="1", KERNEL=="eth*",
NAME="eth0"
but on reboot, I get the error:
Bringing up interface eth0: Device eth0 does not seem to be present,
delaying initialization.
[FAILED]
and the ethernet comes up as eth1 and the eth1 line is added to
/etc/udev/rules.d/70-persistent-net.rules
Almost as if there is something else that needs changing.

Ah. A bit:
# cat /etc/udev/rules.d/70-persistent-net.rules
# This file was automatically generated by the /lib/udev/write_net_rules
# program, run by the persistent-net-generator.rules rules file.
#
# You can modify it, as long as you keep each rule on a single
# line, and change only the value of the NAME= key.
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:c4:03:82:c1:5
3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
# net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="02:c3:04:01:77:c
3", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
===
So I can pull that eth1 line that got generated error and change the
eth0 line?
Well I did that, took the macaddr and hwaddr lines. restarted network
and it was not finding eth0. And it added eth1 back into
/etc/udev/rules.d/70-persistent-net.rules.
I cleaned that up, and rebooted. During the boot, I see the message:
Bringing up interface eth0: Device eth0 does not seem to be present,
delaying initialization.
[FAILED]
and once I get started, ifconfig reports eth1 again, and the eth1 line
got added to rules. But the network IS working with addresses I want.
But on eth1 with the errors about eth0.
So there seems to be something before rules that is needed to be edited,
or there is some limitation on my driver(s).

The keyword must be followed by the name of the hardware class and the printable ASCII equivalent of the hardware address. Hardware classes currently supported include ether (Ethernet), ax25 (AMPR AX.25), ARCnet and netrom (AMPR NET/ROM). The important item is of course "if the device driver supports this operation". If not then a tool downloaded from the NIC manufacturer might be the only way.

[CentOS] Trying to override MAC addr
I am trying to override the mac addr. Now this is on an armv7 actually running the F19 kernel and Redsleeve 6, but it SHOULD be standard Centos6 ifcfg-eth0 content. Of course RSEL does not start with a ifcfg-eth0 file, letting network services do all the work, so I am starting from scratch, using the file from one of my C6 boxes with static addressing. My file has in it: DEVICE="eth0" BOOTPROTO=none NM_CONTROLLED="no" ONBOOT="yes" TYPE="Ethernet" NAME="System eth0" DNS1=208.83.67.188 GATEWAY="208.83.67.177" IPADDR="208.83.67.179" HOSTNAME="rigel2.htt-consult.com" IPV6INIT="yes" MACADDR=02:67:15:00:01:79 MTU=1500 And when I restart network, it can't find eth0: # service network restart Shutting down loopback interface: [ OK ] Bringing up loopback interface: [ OK ] Bringing up interface eth0: Device eth0 does not seem to be present, delaying initialization.

Hi Dan -
I know EXACTLY what virsh is being called for. I wrote the script! It has
nothing to do with logrotate. I want virsh to tell logwatch what the status
is of all virtual machines running on the host. Logwatch will then include
that in its daily summary report. SELinux is getting in the way.

I'm not quite sure what you mean by that. For the alternatives setup I have links on /usr/bin or whatever pointing to other links on /etc/alternatives, which in turn point to the real files - where direct links from /usr/bin would of course be simpler. Perhaps you were talking about something else, or are the locations different on CentOS 7 (I'm using version 6.) What I was referring to is that I believe it's considered as incorrect to put "dynamic" data on /usr these days. I'm not sure there is a separate specification saying so, or if it's just taken to be implied by the FHS (http://www.pathname.com/fhs/pub/fhs-2.3.html). - T > It may also be useful to be able to set up a system-wide default for user applications "with alternatives", but I suppose a user override ought to be possible in that case. > what if I have one user that wants JDK6 and another that needs JDK7 ? I guess the "preferred applications" system in the desktop is in a way meant for such cases, but this of course comes across as incomplete, too. >>> The concept used for 'software collections' is a more realistic >>> approach - but instead of hiding where things land and needing a tool >>> to set up use, why not just tell people what to add to their own PATH >>> and LD_LIBRARY path to get the version you want.
