[zfs-discuss] ZFS Usage on drives
Hello again, I'm wondering if we can see the amount of usage for a drive in ZFS raidz mirror. I'm in the process of replacing some drives but I want to replace the less used drives first (maybe only 40-50% utilisation). Is there such a thing? I saw somewhere that a guy had 3 drives in a raidz, one drive only had to be resilvered 612Gb to replace. I'm hoping as theres quite a bit of free space that some drives only occupy a little and therefore only resilver 200-300Gb of data. Thanks, Andre _ New, Used, Demo, Dealer or Private?

[zfs-discuss] zfs replace multiple drives
Is it safe or possible to do a zpool replace for multiple drives at once? I think I have one of the troublesome WD Green drives as replacing it has taken 39hrs and only reslivered 58Gb, I have another two I'd like to replace but I'm wondering whether I should do that now as the other is being resilvered or wait till (a month) till this has finished.

Re: [zfs-discuss] zfs replace multiple drives
Also, I don't have a feel for how replacing more than 1 drives in a RaidZ[23] affects resilver performance. Thats okay Erik, you've provided the information I need. This is a RAIDZ zpool, I think I'll wait and see how it goes before moving on. I cried seeing 673hrs remaining at 7% completion, the price we pay for being green (and cheap!).

Cheers, Andre You can replace drives up to the number of redundant drives in your vdev, without loosing data. Thus: 2-way mirror:1 drive 3-way mirror:2 drives N-way mirror:N-1 drives RaidZ1: 1 drive RaidZ2: 2 drives RaidZ3: 3 drives If you have more than 1 vdev in a pool, then the above rule apply to EACH vdev. Of course, if you replace the maximum number above, you have no protection against failure for the period it takes to rebuild/resilver the vdev. Also, I don't have a feel for how replacing more than 1 drives in a RaidZ[23] affects resilver performance. -- Erik Trimble Java System Support Mailstop: usca22-123 Phone: x17195 Santa Clara, CA _ New, Used, Demo, Dealer or Private?

[zfs-discuss] Tank zpool has tanked out :(
Hi there, My zpool tank has been chugging along nicely but after a failed attempt at offlining a misbehaving drive I've got a wierd sitation. pool: tank state: DEGRADED status: One or more devices has been taken offline 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: none requested config: NAMESTATE READ WRITE CKSUM tankDEGRADED 0 0 0 raidz1-0 DEGRADED 0 0 0 c7t0d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 c7t3d0 OFFLINE 0 0 0 errors: No known data errors Why does that particular drive appear twice? I am on SNV_134. They are 6x500Gb Western Digital RE drives. I have a spare 500Gb on another controller (c0t0d0) which I want to use to keep replace the (probably dying) drive but I'm not sure I can do this and it will correctly remove the one I want: # zpool replace tank c7t3d0 c0t0d0 Any ideas?

Re: [zfs-discuss] Tank zpool has tanked out :(
Hello Cindy, Does the pool tank actually have 6 disks c7t0-c7t5 and c7t3d0 is now masking c7t5d0 or it is a 5-disk configuration with c7t5 repeated twice? There are 6 disks connected onto the onboard Intel SATA controller (this is a home NAS). There are another four that represent 2x for the rpool and 2x for another zpool for backup snapshots from our Macs. The thing is that I removed the motherboard and everything from the case to see which drive was causing issues, I may have swapped the order of the drives around and confused ZFS. What does the format utility display for these devices? Format presents it correctly. 4. c7t0d0 /p...@0,0/pci1458,b...@11/d...@0,0 5. c7t1d0 /p...@0,0/pci1458,b...@11/d...@1,0 6. c7t2d0 /p...@0,0/pci1458,b...@11/d...@2,0 7. c7t3d0 /p...@0,0/pci1458,b...@11/d...@3,0 8. c7t4d0 /p...@0,0/pci1458,b...@11/d...@4,0 9. c7t5d0 /p...@0,0/pci1458,b...@11/d...@5,0 others on this list have resolved this problem by exporting and importing the pool.
