Hi,
Here is the setup I have:
FreeBSD8.1 running as VM in ESXi server, and accessing 3 RAW mapped devices which are 500G SATA drives. These devices are partitioned in GPT ( labeled) and the partitions make up a RAID5 zpool. About a week ago I ran a scrub on the pool and got alot of errors, which were fixed by zfs. I started running scrub on cron every night and today I got few more errors, decided to reboot the VM. After the boot the zpool was in failed state, thought I could export and import it, but after the export could not import it any more. The drives are /dev/da0, da1, da2 ( da0p1, da1p1, da2p1 used to be the partitions ), there are no IO errors in dmesg or /var/log/messages.
When I checked /dev/ for the device files I can only see da0p1 and none of the respected files for the other 2 devices, running `gpart show` is showing only that one drive as being GPT partitioned.
My understanding is that the partition scheme on the drives got fubared for some reason, and now they don't show as GPT partitioned.
Can I somehow remake the drives as GPT but not touch the actual partition on which ZFS resides, so I can hopefully bring it online and recover my data.
Or any other ideas would be appreciated.
