Hello, What is the access algorithm used within multi-component pools for a given pool, and does it change when one or more members of the pool become degraded ? examples: zpool create mtank mirror c1t0d0 c2t0d0 mirror c3t0d0 c4t0d0 mirror c5t0d0 c6t0d0 or; zpool create ztank raidz c1t0d0 c2t0d0 c3t0d0 raidz c4t0d0 c5t0d0 c6t0d0 As files are created on the filesystem within these pools, are they distributed round-robin accross the components, or do they stay with the first component till full then go to the next,...

1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it in terms of RAID5 I would expect to get (4-1)x18 worth of drive space, but DF -h shows 4x18. Is this a bug or do I not understand? 2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB drives and I want to make a RAIDZ of all of them I would expect the 18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

I installed the latest Solaris 10 on a x4200 with 8gig of ram and two Sun SAS controllers, attached two sas-jbods with 8 SATA-HDDs each und created a zfs pool as a raid 10 by doing something like the following: [i]zpool create zfs_raid10_16_disks mirror c3t0d0 c4t0d0 mirror c3t1d0 c4t1d0 mirror c3t2d0 c4t2d0 mirror c3t3d0 c4t3d0 mirror c3t4d0 c4t4d0 mirror c3t5d0 c4t5d0 mirror c3t6d0 c4t6d0 mirror c3t7d0 c4t7d0[/i] the i set "noatime" and ran the following filebench tests: [i] root at sun1 # ./filebench filebench> load fileserver 12746:...

As mentioned last night, we''ve been reviewing a proposal for hot spare support in ZFS. Below you can find a current draft of the proposed interfaces. This has not yet been submitted for ARC review, but comments are welcome. Note that this does not include any enhanced FMA diagnosis to determine when a device is "faulted". This will come in a follow-on project, of which some

...Raid-5 disk, I tried to create a single zpool on that disk. Again, the same performance problems as noted earlier. Then I partitioned the disk into a 100 GB partition and tried to create a zpool on that. Again, no luck. Performance still stinks. FWIW, format reports the xraid disks as: 2. c3t0d0 <APPLE-Xserve RAID-1.50-2.73TB> /pci at 0,0/pci1022,7450 at b/pci1000,1010 at 1,1/sd at 0,0 3. c3t1d0 <APPLE-Xserve RAID-1.50-2.73TB> /pci at 0,0/pci1022,7450 at b/pci1000,1010 at 1,1/sd at 1,0 4. c3t2d0 <APPLE-Xserve RAID-1.26-745.21GB>...
