Re: [zfs-discuss] how to replace failed vdev on non redundant pool?
well, I was expecting/hoping that this command would work as expected: zpool create testpool vdeva vdevb vdevc *zpool replace testpool vdevc vdevd.* # zpool status reports the disk is reslivered. On a (non-mirror or raid) test pool i just created, this command works. However, when the disk failed, all I/o was suspended, and I could not replace it as above. Even if I forced the command with -f. If this were a raidz pool, would the zpool replace command even work? - Cassandra (609) 243-2413 Unix Administrator From a little spark may burst a mighty flame. -Dante Alighieri On Fri, Oct 15, 2010 at 10:06 PM, Edward Ned Harvey sh...@nedharvey.comwrote: From: zfs-discuss-boun...@opensolaris.org [mailto:zfs-discuss- boun...@opensolaris.org] On Behalf Of Cassandra Pugh I would like to know how to replace a failed vdev in a non redundant pool?

This obviously worked since the device you were about to replace was still accessible, which isn't the case if a device inside a vdev fails and the vdev itself it not redundant. On a (non-mirror or raid) test pool i just created, this command works. However, when the disk failed, all I/o was suspended, and I could not replace it as above. Even if I forced the command with -f. If this were a raidz pool, would the zpool replace command even work? Yes this would work in raidz pool, since you have a redundancy of 1, so one device may go offline, before the vdev fails. -- Stephan Budach Jung von Matt/it-services GmbH Glashüttenstraße 79 20357 Hamburg Tel: +49 40-4321-1353 Fax: +49 40-4321-1114 E-Mail: stephan.bud...@jvm.de Internet: http://www.jvm.com Geschäftsführer: Ulrich Pallas, Frank Wilhelm AG HH HRB 98380 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] how to replace failed vdev on non redundant pool?
Hello, I would like to know how to replace a failed vdev in a non redundant pool? I am using fiber attached disks, and cannot simply place the disk back into the machine, since it is virtual. I have the latest kernel from sept 2010 that includes all of the new ZFS upgrades. Please, can you help me? - Cassandra (609) 243-2413 Unix Administrator From a little spark may burst a mighty flame. -Dante Alighieri ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] how to replace failed vdev on non redundant pool?
If the pool is non-redundant and your vdev has failed, you have lost your data. Just rebuild the pool, but consider a redundant configuration.
