Hi All,
I hope this is the correct place for this question as I think it was ZFS that saved me. A little while ago I did some thing very silly in a moment of non concentration... I meant to use dd to copy an image (around 500Mb) to a USB disk but instead wrote over a non raided zfs disk! This of course stopped the zpool from operating, I fiddled around trying to repair the problem and ended up having to reboot the server as I had ended up with many hung process trying to read the disk. I am using Solaris 11, in my x86 HP Microserver n36l with sata disks. Below is various status output's: My question is how after a reboot did the disk / zpool recover with from what I have seen so far no corruption at all? root@n36l:/export/home/drowl# zpool status -x pool: data2 state: SUSPENDED status: One or more devices are faulted in response to IO failures. action: Make sure the affected devices are connected, then run 'zpool clear'. see: http://www.sun.com/msg/ZFS-8000-HC scan: none requested config: NAME STATE READ WRITE CKSUM data2 UNAVAIL 0 0 0 experienced I/O failures c2t0d0s0 UNAVAIL 0 0 0 experienced I/O failures I guessing from the below its the label / partition that is busted... root@n36l:/export/home/drowl# prtvtoc /dev/rdsk/c2t0d0s2 prtvtoc: /dev/rdsk/c2t0d0s2: Unable to read Disk geometry errno = 0x5 root@n36l:/export/home/drowl# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c2t0d0 <drive type unknown> /pci@0,0/pci103c,1609@11/disk@0,0 ...
