Re: [zfs-discuss] Strange problem, possibly zfs/zpool
OK problem solved. I had incorrectly assumed that the server wasn't booting, the longest I had left it was over night and there was still no logon prompt in the morning! The reality is that it was just taking a very long time due to an excessive amount of automatically created snapshots by Time Slider. It did occur to me earlier that the amount of snapshots might cause delays mounting the pool as I had previously left Time Slider on for all filesystems and volumes. Back then I used Time Slider to erase the snapshots, again, incorrectly assuming it would also erase the volume snapshots, I can now confirm that it does not! So, to resolve, I reinstalled the OS (installing another instance to another disk would work), imported the array, the import command then seems to get stuck (obviously, in hindsight), although the core filesystems are present and accessible. Now, before rebooting, I then run this command to erase all automatically created snapshots: zfs list -r -t snapshot -o name -H array/iscsi | grep zfs-auto-snap | xargs -t -l zfs destroy Obviously, this takes while ;-) After this completes, I reboot and all is well again! -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Intel X25-E SSD in x4500 followup
I can confirm that on an X4240 with the LSI (mpt) controller: X25-M G1 with 8820 still returns invalid selftest data X25-E G1 with 8850 now returns correct selftest data (I haven't got any X25-M G2) Going to replace an X25-E with the old firmware in one of our X4500s soon and we'll see if things work right there) I still see heavy write load-induced bus resets with the 8850-firmware X25-Es on the X4240 though.

[zfs-discuss] Reboot seems to mess up all rpools
[Originally posted to indiana-discuss] On certain X86 machines there's a hardware/software glitch that causes odd transient checksum failures that always seem to affect the same files even if you replace them. This has been submitted as a bug: Bug 11201 - Checksum failures on mirrored drives - now CR 6880994 P4 kernel/zfs Checksum failures on mirrored drives We have SPARC based ZFS servers where we keep a copy of this rpool so we can more easily replace the damaged files (usually system libraries). In addition, to check the validity of the zfs send stream of the ZFS server rpool, there's a copy of that as well. For good reasons there might be several rpools in this data pool at any given time. When the ZFS server is rebooted, it tries to update the boot archive of every rpool it can find, including the X86 archive, which fails because it's the wrong architecture. The ZFS server is currently at snv103, but the backup server has an additional disk with snv111b on it, which was recently updated to snv122. However, if you boot snv103 and then reboot, it will also update the snv122 boot archive, rendering snv122 unbootable. All versions up to and including snv122 exhibit this behavior. I'm not sure why updating the boot archive would do this, but surely this is a bug. Reboot should only update it's own archive, and not any ZFS archives at all if it is running from UFS. Before submitting a bug report, I thought I'd check here to see if a) if this is has already been reported, and b) if I have the terminology right.

Re: [zfs-discuss] zpool status OK but zfs filesystem seems hung
Thanks for the reply but this seems to be a bit different. a couple of things I failed to mention; 1) this is a secondary pool and not the root pool. 2) the snapshot are trimmed to only keep 80 or so. The system boots and runs fine. It's just an issue for this secondary pool and filesystem.It seems to be directly related to I/O intensive operations as the (full) backup seems to trigger it, never seen it happen with incremental backups...

[zfs-discuss] zpool status OK but zfs filesystem seems hung
Hello all, I have a situation where zpool status shows no known data errors but all processes on a specific filesystem are hung. This has happened 2 times before since we installed Opensolaris 2009.06 snv_111b. For instance there are two files systems in this pool 'zfs get all' on one filesystem returns with out issue when ran on the other filesystem it hangs. Also a 'df -h' hangs, etc. This file system has many different operation running on it; 1) It receives incremental snapshot every 30 minutes continuously. 2) every night a clone is made from one of the received snapshot streams then a filesystem backup is taken on that clone (the backup is a directory traversal) once the backup completes the clone is destroyed. We tried to upgrade to the latest build but ran in to the current 'check sum' issue in build snv_122 so we rolled back. # uname -a SunOS lahar2 5.11 snv_111b i86pc i386 i86pc # zpool status zdisk1 pool: zdisk1 state: ONLINE scrub: none requested config: NAMESTATE READ WRITE CKSUM zdisk1 ONLINE 0 0 0 raidz1ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0 0 c7t5d0 ONLINE 0 0 0 spares c7t6d0AVAIL errors: No known data errors The filesystem is currently in this 'hung' state, is there any commands I can run to help debug the issue?

[zfs-discuss] ZFS and quota/refqoutoa question
All, IHAC that is asking the following...reviewing the following document http://docs.sun.com/app/docs/doc/817-2271/6mhupg6nc it appears it may not for the parent setting will transcend downwards to the child Can anyone elaborate if this is correct or not.. Thanks Peter the question is regarding to filesystem hierarchy and quota and refquota usage. tank/appswill be mounted as /apps -- need to be set with 10G tank/apps/data1 will need to be mount as /apps/data1, need to be set with 20G alone. The question is: If refquota is being used to set the filesystem sizes on /apps and /apps/data1. /apps/data1 will not be inheriting the quota from /apps. In other words, /apps/data1 will have full 20G usable disk space and /apps will have 10G usable disk space. /apps/data1 will not be inherting disk space from /apps. -- Peter Wilk Technical Support Engineer Sun Microsystems, Inc.
