I have one storage server with 24 drives, spread across three controllers and split into three RAIDz2 pools. Unfortunately, I have no idea which bay holds which drive. Fortunately, this server is used for secondary storage so I can take it offline for a bit. My plan is to use zpool export to take each pool offline and then dd to do a sustained read off each drive in turn and watch the blinking lights to see which drive is which. In a nutshell: zpool export uberdisk1 zpool export uberdisk2 zpool export uberdisk3 dd if=/dev/rdsk/c9t0d0 of=/dev/null dd if=/dev/rdsk/c9t1d0 of=/dev/null [etc. 22 more times] zpool import uberdisk1 zpool import uberdisk2 zpool import uberdisk3
Are there any glaring errors in my reasoning here? My thinking is I should probably identify these disks before any problems develop, in case of erratic read errors that are enough to make me replace the drive without being enough to make the hardware ID it as bad. -- Dave Pooser, ACSA Manager of Information Services Alford Media http://www.alfordmedia.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
