Re: [zfs-discuss] Can't rm file when "No space left on device"...

It's probably this bug: http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6453407 We've been affected by the same problem on our X4500 Thumpers. Although the bug report claims a fix was delivered in solaris_nevada(snv_70), I've yet to see an official patch released for it (we run Sola

Re: [zfs-discuss] ZFS fragmentation

Lance, This could be bug#*6596237 Stop looking and start ganging .* The fix is in progress and Victor Latushkin is working on it. We have an IDR based on the patches 127127-11/127128-11 which has the first cut of the fix. You could raise an escalation

[zfs-discuss] Sparc rpool mirror failed

Hi All, I have just installed b90 on an E250 with 2 identical SCSI disks and zfs root. But I keep getting the error cannot attach /dev/rdsk/c0t8d0 to c0t0d0s0: device is too small when I execute zpool attach rpool c0t0d0s0 /dev/rdsk/c0t8d0 It appears to be a labelling

[zfs-discuss] Performance issues ZFS / CIFS on home file server

I'm setting up a home file server on opensolaris b86 My system is running with AMD Athlon 4400+, 1GB ram, rge 100Mb/s ethernet I'm able to create the CIFS shares and able to access the data from my windows laptop. Now, when i try to stream some HD video the performace is pretty bad, to the exte

Re: [zfs-discuss] zpool iostat

I was using a 5 minute interval. I did another test with 1 second interval: data1 41.6G 5.65G 0 0 63.4K 0 data2 58.2G 9.81G 0447 0 2.31M So, the 63K read bandwidth doesn't show any read operations still. Is that still rounding? What exactly is an op

Re: [zfs-discuss] zpool iostat

A three-way mirror and three disks in a double parity array are going to get you the same usable space. They are going to get you the same level of redundancy. The only difference is that the RAIDZ2 is going to consume a lot more CPU cycles calculating parity for no good cause. In this case,

Why is it that the read operations are 0 but the read bandwidth is >0? What is iostat [not] accounting for? Is it the metadata reads? (Is it possible to determine what kind of metadata reads these are? I plan to have 3 disks and am debating what I should do with them, if I should do a raidz (si

Re: [zfs-discuss] ZFS fragmentation

Any progress on a defragmentation utility? We appear to be having a severe fragmentation problem on an X4500, vanilla S10U4, no additional patches. 500GB disks in 4 x 11 disk RAIDZ2 vdevs. It hit 97% full and fell off a cliff...about 50KB/sec on writes. Deleting files so the zpool is at 92%

Re: [zfs-discuss] [zones-discuss] Rcapd threshold vs ZFS cache

ZFS cache memory is not considered free. rcapd uses the sysconf(_SC_AVPHYS_PAGES) interface to get the amount of free memory. One possibility could be to alter sysconf to report some about of the zfs cache as free. -Steve L. On Wed, Jun 18, 2008 at 01:18:07PM -0500, Brian Smith wrote: > When rca
