I seem to have managed to end up with a pool that is confused abut its children disks. The pool is faulted with corrupt metadata: pool: d state: FAULTED status: The pool metadata is corrupted and the pool cannot be opened. action: Destroy and re-create the pool from a backup source. see: http://illumos.org/msg/ZFS-8000-72 scan: none requested config: NAME STATE

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 --

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,

CentOS Community, What commands can I use to check the disk health of the system when LVM2 is being used on top of a RAID 10 using a HARDWARE 3ware raid card. The OS sees a hardware raid usually as one big drive. Is there a way to check the disks individually to see if any are failing, or throwing hard or scsi transport errors?

I'm running FreeBSD 7.1-PRERELEASE over Asus P5Q motherboard. Such board comes with an nic requiring age0 driver. When the nic is under load, such trasferring big amount of data over gigabit connection (let's say some gigabyte backups), the computer hangs, sometimes with panic, sometimes freezing. Before that i was using an Intel nic with em0 driver and 7.0-Stable#2.. and that

...serial number. smartctl, hdparm, udevinfo, /dev/disk/by-uuid, or /dev/disk/by-id. However, the 3ware card obfuscates the drives from the OS and those methods don't work. The only way I know how to get a drives serial number is via the smartctl command like "smartctl -d 3ware,[0-15] -i /dev/twa0", but that does not tell me which sd[a-z] the drive is assigned to. Here is what I have tried. Creating a single large partition with fdisk on each drive as linux autoraid to get a uuid. for some reason the OS assigns the same uuid and only one uuid to the last drive I partition from the 3war...

If you have a RAID5 array, then you have one volume spread across the physical disks.? You can then

Hi, I've got a new server with a 3ware 9550SXU with the Battery. I am using FreeBSD 7.0-Release (tried both 4BSD and ULE) using AMD64 and the 3ware performance for writes is just plain horrible. Something is obviously wrong but I'm not sure what. I've got a 4 disk RAID 10 array. According to 3dm2 the cache is on. I even tried setting The StorSave preference to
