I tried clearing the fault, and now the original disk and the 1st replacement are both offline replacing-0 UNAVAIL 0 0 0 insufficient replicasĪt this point, what should I do to get the new replacement disk resilvering? Doing zpool replace on the original disk or the first replacement just yields the error (slightly shortened here) "cannot open 'c4t500.' no such device in /dev/dsk. However, the zpool status still showed the old disk. This is provided by a file system that is usually mounted on /etc/mnttab. The table of currently mounted file systems can be found by examining the mounted file system information file. I restarted the machine to clear out old state, then cfgadm -al showed just c8 scsi-sas connected configured unknown umount unmounts a currently mounted file system, which may be specified either as a mountpoint or as special, the device on which the file system resides. The new disk is there, but the old one hasn't gone away. I hot-swapped the disk, and then cfgadm -al showed c8 scsi-sas connected configured unknownĬ8::w50014ee6ad8f0df2,0 disk-path connected configured unknownĬ8::w50014ee658315c1d,0 disk-path connected unconfigured unknown I suspected it wouldn't, but it was easy to try. We have already examined mount command in the following tutorial. I decided to try another disk, and see if that made any difference. Linux distributions like Ubuntu, Debian, CentOS, RHEL, and others use disks by mounting them to the file system. At this point zpool status for the problem disk shows replacing-0 UNAVAIL 0 0 0 insufficient replicasĬ4t50014EE658315C1Dd0 FAULTED 0 0 0 too many errors It started resilvering, and after a while had the same problem. Id do a plain backup first of its data with dd to some other medium, then use e2fsck to try to repair it. Your disk wasnt unmounted cleanly and/or may even be corrupted. Dmesg showed " SYNCHRONIZE CACHE command failed." I wondered if it might be a loose cable, so shut down the machine, reseated the disk and cables and started it up again. sdb 8:16 0 1.1T 0 disk sdb1 8:17 0 1.1T 0 part ext4 b6ff3b3e-6e00-4279-8d6f-7341bbbfba88. create a bootable USB setup stick You can setup OmniOS from USB (use usb-dd file, 1 GB+ USB stick) or CD (.iso) You can use this imager image.zip to transfer the usb image to your stick (Windows) 2. It started to resilver, and then the replacement disk had errors. In the Disk Utility app on your Mac, select the volume you want to mount. I took the problem disk offline, replaced it with a new disk, and got the new disk reconfigured. In a raidz3 pool with 11 disks on OmniOS r151010, one of the disks went bad. A disk replacement in ZFS went awry, and now the replacing disk, even though no longer physically present, is "stuck" in the pool, blocking further replacement attempts.
