In order to back up the ZFS root pool on my laptop I plug in a USB hard disk and attach slice 0 on it as a mirror to the slice on the laptop's internal hard disk. Sometimes after a while the resilvering will stop and zpool status report this:
and...@grissom:~# zpool status pool: rpool state: DEGRADED status: One or more devices has been removed by the administrator. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Online the device using 'zpool online' or replace the device with 'zpool replace'. scrub: resilver in progress for 0h14m, 70.86% done, 0h6m to go config: NAME STATE READ WRITE CKSUM rpool DEGRADED 0 0 0 mirror-0 DEGRADED 0 0 0 c2t0d0s0 ONLINE 0 0 0 c5t0d0s0 REMOVED 0 0 0 5.02G resilvered errors: No known data errors c5t0d0s0 being the USB hard disk. The "format" command gets stuck looking for disks once this happens, until after a few minutes when I get odd noises from the drive, and it then sounds like it is spinning back up. Once it does ZFS noticed it has returned and continues resilvering. Here is the output of the format command showing the device paths: AVAILABLE DISK SELECTIONS: 0. c2t0d0 <DEFAULT cyl 5097 alt 2 hd 255 sec 63> /p...@0,0/pci1179,1...@1f,2/d...@0,0 1. c5t0d0 <drive type unknown> /p...@0,0/pci1179,1...@1a,7/h...@6/stor...@3/d...@0,0 Specify disk (enter its number): Attached is the output of prtconf -v. The system is a Tecra M10 laptop. How can I find out what is going on here? The disk may be suspect, but it would be nice to know why it is getting reported as "disk has gone away". Thanks Andrew. -- This message posted from opensolaris.org _______________________________________________ opensolaris-help mailing list opensolaris-help@opensolaris.org
