We have about 50 CentOS servers with software RAID level 1 (mirroring). Each week, we swap out one of the drives (the one in the second of four hot-swap bays, only the first two of which contain drives) on each server and take them offsite for safekeeping. The problem is, the kernel seemingly randomly switches between /dev/sdb and /dev/sdc for these devices. This makes the process slower by

I updated the machine that I use for a web/email server last night to 5.9, and I have this in the logwatch report this morning: QUOTE: --------------------- Smartd Begin ------------------------ Warnings: Device: /dev/sda [SAT], WARNING: There are known problems with these drives, - 1 Time(s) **Unmatched Entries** smartd 5.42 2011-10-20 r3458 [x86_64-linux-2.6.18-348.el5] (local

Hi All, I don't know enough about when errors are *really* errors. So I google a lot to read and learn. I have a few things in my Logwatch that I want to make sure I understand 1. smartd **Unmatched Entries** Problem creating device name scan list Device /dev/sda: using '-d sat' for ATA disk behind SAT layer. Device /dev/sdb: using '-d sat' for ATA disk behind SAT layer.

Is there a document with instructions for this? I've had smartd warnings that a hard disk in my server is sick, so I am installing a new drive (in addition to the old). I was thinking of copying the old root partition with sudo cp -a -P /* /mnt/hd (after mounting the prospective new root partition). Then I'd have to modify the new /etc/fstab . Is that a sensible approach? -- Timothy

I have a usb drive, /media/disk and I want to reformat it. There are several questions that come up: How can I determine the current format? Do I use the mkfs command? Many thanks... Todd -- Ariste Software Petaluma, CA 94952 http://www.aristesoftware.com

Yohoo! I have some issues with the smartd in CentOS5/x64 I edited the /etc/smartd.conf for my needs and restarted the smartd with "service smartd restart". But the start script is overriding my file. I checked it and saw the following lines: ---------------/etc/init.d/smartd------------ case "$1" in start | reload | restart) GEN_CONF="*SMARTD*AUTOGENERATED*" [ !

last night I checked the log messages on the server Dell PE2950 6xSAS 146G I found the smartd running , I did not request such daemon [root at PowerEdge1 pons]# tail -f /var/log/messages Aug 25 08:27:30 PowerEdge1 smartd[8039]: Home page is http://smartmontools.sourceforge.net/ Aug 25 08:27:30 PowerEdge1 smartd[8039]: Opened configuration file /etc/smartd.conf Aug 25 08:27:30 PowerEdge1

It seems I can't smarm monitor disks on RAID controllers? I tried on several machines with two different controllers and on all I get this when starting up smartd: Jul 27 14:36:43 c1 smartd[5944]: Opened configuration file /etc/smartd.conf Jul 27 14:36:43 c1 smartd[5944]: Configuration file /etc/smartd.conf parsed.

Hi, I've CentOS5 box with 3ware RAID controller in it. I can't get the tw_cli command line tool to work, and smartd also barks on me. The tw_cli simply doesn't see the controller, no errors logged anywhere. When starting smartd, it is much more verbose. I'm getting a bunch of messages like this: Oct 9 22:15:15 toporko kernel: program smartd is using a deprecated SCSI ioctl,

I decided, after the last discussion of smartd and S.M.A.R.T. disks, to take a look in my /var/log/messages, and I'm seeing fair bit of this: Sep 10 20:11:23 mhrichter smartd[3361]: Device: /dev/sda, 4294967295 Offline uncorrectable sectors Sep 10 20:41:23 mhrichter smartd[3361]: Device: /dev/hdb, 21 Currently unreadable (pending) sectors Sep 10 20:41:24 mhrichter smartd[3361]: Device:

Hello, I'm using HP homeserver where host system run CentOS 6.3 with KVM virtualization with SELinux enabled, guests too run the same OS (but without SELinux, but this does not matter). Host system installed on mirrors based on sda and sdb physical disks. sd{c..f} disks attached to KVM guest (whole disks, not partitions; needed to use zfs (zfsonlinux) benefit features). Problem is that disks

How can I tell wich HDD to swap, when the "cat /proc/mdstat" says one HDD of the RAID1 array has died? Does the HDD's has some serial numbers, that I can see in "reality", and I can get that number from e.g.: a commands output? How could I know wich HDD to swap in e.g.: a RAID1 array? thank you -------------- next part -------------- An HTML attachment

I'm looking to do a bit more monitoring of my 3ware 9550 with smartd, and wanted to see what others were doing with smart for monitoring 3ware hardware. Do you have the smartd.conf configured to test, or simply monitor health status? Are you monitoring the drive as centos sees it (/dev/sdX) or are you using the 3ware /dev/twaX for monitoring? Opinions and discussions are welcome :-P --

I am trying to install a CentOS 6.4 x86_64 VM using a CentOS 5.9 x86_64 host, but its install has froze *twice*. What I am doing is to create a 10gig LVM volume, which I put a MS-DOS partition table on (using fdisk). I then format the only partition to ext3, install grub and install the pxeboot kernel and initrd.img and a simple grub.conf to load this. I have the CentOS 6.4 x86_64 ISOs mounted

Is it even remotely possible to run MacOSX (or Darwin) as VM under CentOS 5.10 / xen? Or am I better off not even trying and just getting a MacMini or MacBook to just jack into my LAN? I just need a 'build box' and possibly something to do light testing (eg does the program run? Does the GUI come up?). I don't really have the *physical* room for an iMac, unless the screen is tiny.

I have begun to notice that the smartd stalls my machine's boot process for as much as 2-3 minutes while it is coming up. I have the BIOS SMART function enabled, and I removed the bad SG400GB drive from the box yesterday, but I think this goes back farther than that. Why does it take so long? Is the BIOS SMART involved in this (and how)? Also, sendmail and sm-client take 30s-2m to come up

One of my VPS stopped working. After the data centre replaced a disk normal service resumed, then I notices this: CentOS release 5.5 (Final) Kernel 2.6.35.4 on an x86_64 I always thought Centos 5.x would always be on 2.6.18. Any thoughts?
