similar to: ZFS disk failure question

I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact. I want zfs to get access to the full disk instead of a slice. I believe like c8d0 instead off c8d0s1. I wanted to do this 1 disk at a time and let it resilver. what is the proper way to do this. I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1 but it didn''t let me do that. then I

So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

Hi all I have installed a new server with 77 2TB drives in 11 7-drive RAIDz2 VDEVs, all on WD Black drives. Now, it seems two of these drives were bad, one of them had a bunch of errors, the other was very slow. After zfs offlining these and then zfs replacing them with online spares, resilver ended and I thought it''d be ok. Appearently not. Albeit the resilver succeeds, the pool status

Hi, Is it possible to convert a zfs pool from a concatenation of 2 disks to a 2 way mirror without backing up the data, re-creating the pool and restoring it. i.e diskA,diskB ----> mirror(diskA,diskB) Thanks, Jeff

Hi, once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones. Thanks, budy -- This message posted from opensolaris.org

Hi all I''m seeing some rather bad resilver times for a pool of WD Green drives (I know, bad drives, but leave that). Does resilver go through the whole pool or just the VDEV in question? -- Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy at karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres

I''m using zfs not to have access to a fail-safe backed up system, but to easily manage my file system. I would like to be able to, as I buy new harddrives, just to be able to replace the old ones. I''m very environmentally concious, so I don''t want to leave old drives in there to consume power as they''ve already been replaced by larger ones. However, ZFS

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

Hi, one quick&dirty way of backing up a pool that is a mirror of two devices is to zpool attach a third one, wait for the resilvering to finish, then zpool detach it again. The third device then can be used as a poor man''s simple backup. Has anybody tried it yet with a striped mirror? What if the pool is composed out of two mirrors? Can I attach devices to both mirrors, let them

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

I am curious why zpool status reports a pool to be in the DEGRADED state after a drive in a raidz2 vdev has been successfully replaced. In this particular case drive c0t6d0 was failing so I ran, zpool offline home/c0t6d0 zpool replace home c0t6d0 c8t1d0 and after the resilvering finished the pool reports a degraded state. Hopefully this is incorrect. At this point is the vdev in question now has

In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz storage pool and then shelved the other two for spares. One of the disks failed last night so I shut down the server and replaced it with a spare. When I tried to zpool replace the disk I get: zpool replace tank c10t0d0 cannot replace c10t0d0 with c10t0d0: device is too small The 4 original disk partition tables look like

I have Solaris 10 U7 that is exporting ZFS filesytem. The client is Solaris 9 U7. I can mount the filesytem just fine but I am unable to write to it. showmount -e shows my mount is set for everyone. the dfstab file has option rw set. So what gives?

Hello All I read this thread Resilver/scrub times? for a few minutes and I have recognize that I dont know the different between Resilvering and Scrubing. Shame on me. :-( I dont find some declarations in the man-pages and I know the command to start scrubing "zpool scrub tank" but what is the command to start resilver and what is the different? -- Best Regards Alexander Dezember, 20

for s10u2, documentation recommends 3 to 9 devices in raidz. what is the basis for this recommendation? i assume it is performance and not failure resilience, but i am just guessing...
