I have zpool like that pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 raidz3-0 ONLINE 0 0 0 ___c6t0d0 ONLINE 0 0 0 ___c6t1d0 ONLINE 0 0 0 ___c6t2d0 ONLINE 0 0 0 ___c6t3d0 ONLINE 0 0 0 ___c6t4d0 ONLINE

In a discussion a few weeks back, it was mentioned that the Best Practices Guide says something like "Don''t put more than ___ disks into a single vdev." At first, I challenged this idea, because I see no reason why a 21-disk raidz3 would be bad. It seems like a good thing. I was operating on assumption that resilver time was limited by sustainable throughput of disks, which

I currently am getting good speeds out of my existing system (8x 2TB in a RAIDZ2 exported over fibre channel) but there''s no such thing as too much speed, and these other two drive bays are just begging for drives in them.... If I go to 10x 2TB in a RAIDZ3, will the extra spindles increase speed, or will the extra parity writes reduce speed, or will the two factors offset and leave things

Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be). A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file

Hi everyone, I have just installed Solaris and have added a 3x500GB raidz drive array. I am able to use this pool (''tank'') successfully locally, but when I try to share it remotely, I can only read, I cannot execute or write. I didn''t do anything other than the default ''zfs set sharenfs=on tank''... how can I get it so that any allowed user can access

Hi, Is it expected that if I have filesystem tank/foo and tank/foo/bar (mounted under /tank) then in order to be able to browse via /net down into tank/foo/bar I need to have group/other permissions on /tank/foo open? # zfs create tank/foo # zfs create tank/foo/bar # chown gavinm /tank/foo /tank/foo/bar # zfs set sharenfs=rw tank/foo # ls -laR /tank/foo /tank/foo: total 9 drwxr-xr-x 3 gavinm

I''ve got a zpool that has 4 raidz2 vdevs each with 4 disks (750GB), plus 4 spares. At one point 2 disks failed (in different vdevs). The message in /var/adm/messages for the disks were ''device busy too long''.

Hello all, We're having problems with files that suddenly stop being seen on the fuse clients. I couldn't yet find a way to reproduce this. It happens every once in a while. Sometimes you try to ls some file and it can't be found. When you run ls on the parent directory, it is shown on the output, and, after that, you can access it. I'm mentioning ls, but the problem also

Hello R experts, I have having a difficult time figuring out how to perform and interpret an ANCOVA of my nested experimental data and would love any suggestions that you might have. Here is the deal: 1) I have twelve tanks of fish (1-12), each with a bunch of fish in them 2) I have three treatments (1-3); 4 tanks per treatment. (each tank only has one treatment applied to it) 3) I sampled

Hello all, We have a distributed volume running in 7 hosts and 28 bricks. We've been experiencing some strange behaviors over the time, some of them are solved when the gluster services are restarted, but other problems persist. In the case below, and this one happens many times, some people access the gluster filesystem via Samba. They have a mapped drive in their windows machine.

I apologize if this has been covered before. I have not seen a blow-by-blow installation guide for Ubuntu onto an iSCSI target. The install guides I have seen assume that you can make a target visible to all, which is a problem if you want multiple iSCSI installations on the same COMSTAR target. During install Ubuntu generates three random initiators and you have to deal with them to get things

Hi all, we have just bought a sun X2200M2 (4GB / 2 opteron 2214 / 2 disks 250GB SATA2, solaris 10 update 4) and a sun STK 2540 FC array (8 disks SAS 146 GB, 1 raid controller). The server is attached to the array with a single 4 Gb Fibre Channel link. I want to make a mirror using ZFS with this array. I have created 2 volumes on the array in RAID0 (stripe of 128 KB) presented to the host

A colleague just asked if zfs delegation worked with zvols too. Thought I''d give it a go and got myself in a mess (tank/linkfixer is the delegated dataset): root at non-global / # zfs create -V 500M tank/linkfixer/foo cannot create device links for ''tank/linkfixer/foo'': permission denied cannot create ''tank/linkfixer/foo'': permission denied Ok, so

Hy all, recently I upgraded to S10U8 a T5120 using LU. The system had a zones configured and at time of upgrade procedure the zones was still alive and worked fine. The LU procedure was ended successfully. Zones on the system was installed in a ZFS filesystem. Here the result at the end of LU (ABE-from: s10Aug2007, ABE-to: s10Set2009): # zfs list NAME USED AVAIL REFER MOUNTPOINT

Just a quick fyi... We''ve recently added support for blktap along with support for managing virtual disks (disk file images). There are some difference from a linux dom0. This is available in b101 @ http://www.opensolaris.org/os/downloads/sol_ex_dvd_1/ This allows you to create and manage vmdk and vdi (Virtual Box) disk files. By default, virt-install will now use a vmdk vdisk when

Hi, I am having a really strange problem with my Samba shares on Debian Buster. None of the users can access any shares, which reside on ZFS-filesystem. Any other share works just fine. For example, if I create a normal folder to /home with same permissions and replace a ZFS-share with that, it works fine. When accessing any ZFS-shares the following error is recorded: Jan 08 22:39:56
