Re: [zfs-discuss] Accidentally mixed-up disks in RAIDZ
Solved! This what I did: boot with the disks unplugged, I took a 'digest -a md5 /etc/zfs/zpool.cache', then I did 'zpool export -f data', I got an error message saying that the pool didn't exist. I checked again the MD5 against the zpool.cache and it effectively changed (so, although the export appeared to fail, it actually did something). I turned off the machine, plugged the disks back in and then I performed a 'zpool import' without any issue. All the properties retain their previous settings. Thanks to all for your tips.

Re: [zfs-discuss] Accidentally mixed-up disks in RAIDZ
No, Chris, I didn't export the pool becasue I didn't expect this to happen. It's an excellent suggestion, so I'll try it when I get my hands on the machine. Thank you. Leandro. De: Chris Murray Para: Leandro Vanden Bosch Enviado: sábado, 7 de noviembre, 2009 19:13:33 Asunto: RE: [zfs-discuss] Accidentally mixed-up disks in RAIDZ Did you export the pool before unplugging the drives? I've had occasions in the past where ZFS does get mixed-up if the machine is powered up with the drives of a currently imported pool, in the wrong order. The solution in the end was to power up without the drives, export the pool, and then import.

[zfs-discuss] Accidentally mixed-up disks in RAIDZ
Hello to you all, Here's the situation: While doing a case replacement in my home storage server I accidentally removed the post-it with the disk number from my three 1TB disks before connecting them back to the corresponding SATA connector. The issue now is that I don't know in which order they should be connected. Do any of you know how can I _safely_ bring the zpool on-line? I didn't plugged'em in yet becasue I'm afraid of losing some valueable personal information. Thanks in advance. Leandro. Yahoo! Cocina Encontra las mejores recetas con Yahoo!
