[zfs-discuss] 'sync' properties and write operations.
Hi. Can you explain to me: 1. dataset has 'sync=always' I start write to file on this dataset in no-sync mode: system write file in sync or async mode? 2. dataset has 'sync=disabled' I start write to file on this dataset in sync mode: system write file in sync or async mode? Thanks. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] zfs lists discrepancy after added a new vdev to pool
On 27 August, 2010 - Darin Perusich sent me these 2,1K bytes:
Hello All,
I'm sure this has been discussed previously but I haven't been able to find
an
answer to this. I've added another raidz1 vdev to an existing storage pool
and
the increased available storage isn't reflected in the 'zfs list' output. Why
is this?
The system in question is runnning Solaris 10 5/09 s10s_u7wos_08, kernel
Generic_139555-08. The system does not have the lastest patches which might
be
the cure.
Thanks!
Here's what I'm seeing.
zpool create datapool raidz1 c1t50060E800042AA70d0 c1t50060E800042AA70d1
Just fyi, this is an inefficient variant of a mirror. More cpu required
and lower performance.

I can't think of an easy way to measure pages that have not been consumed since it's really an SSD controller function which is obfuscated from the OS, and add the variable of over provisioning on top of that.

[zfs-discuss] mirrored pool unimportable (FAULTED)
Hi, more than a year ago I created a mirrored ZFS-Pool consiting of 2x1TB HDDs using the OSX 10.5 ZFS Kernel Extension (Zpool Version 8, ZFS Version 2). Everything went fine and I used the pool to store personal stuff on it, like lots of photos and music. (So getting the data back is not time critical, but still important to me.) Later, since the development of the ZFS extension was discontinued, I tried to move the pool to FreeBSD 8, where I detached one of the drives to use it in another way. (Yes, dumb idea, but I needed the disk and thought I would be fine since it was a mirrored pool) After that the pool was no longer importable - neither on OSX nor on FreeBSD. Since then I tried to access my data with OpenSolaris (build 134), ZFS-Fuse on Ubuntu and FreeBSD 8.1 - so far without any success. I am aware of the -F, -D, -d options of zpool and also tried symlinking in order to match the path of the drives according to the labels. Beyond that I didn´t do much because I was afraid to damage the data which to my understanding should still be intact. I also have to admit that low level filesystem-stuff is a bit above my head. I really hope that someone here can give me a clue or at least a hint about if its worth to continue trying... Now here is what i tried on OpenSolaris: (Drives connected via USB, ZFS Partitions: /dev/dsk/c4t0d0s1, /dev/dsk/c4t0d1s1 ; Symlinks: /dev/da0p2 - /dev/dsk/c4t0d1s1 , /dev/da2p2 - /dev/dsk/c4t0d0s1) j...@opensolaris:~# zpool import Media cannot import 'Media': one or more devices is currently unavailable Destroy and re-create the pool from a backup source. j...@opensolaris:~# zpool import -fF -d /dev/dsk pool: Media id: 6503452912318286686 state: FAULTED status: One or more devices contains corrupted data. action: The pool cannot be imported due to damaged devices or data. see: http://www.sun.com/msg/ZFS-8000-5E config: Media FAULTED corrupted data c4t0d0s1 FAULTED corrupted data Labels: j...@opensolaris:~# zdb -l /dev/dsk/c4t0d0s1 LABEL 0 version: 6 name: 'Media' state: 1 txg: 262869 pool_guid: 6503452912318286686 hostid: 4220169081 hostname: 'mini.home' top_guid: 18181370402585537036 guid: 18181370402585537036 vdev_tree: type: 'disk' id: 0 guid: 18181370402585537036 path: '/dev/da0p2' whole_disk: 0 metaslab_array: 14 metaslab_shift: 30 ashift: 9 asize: 999856013312 DTL: 869 (LABEL 1 - 3 identical) j...@opensolaris:~# zdb -l /dev/dsk/c4t0d1s1 LABEL 0 version: 6 name: 'Media' state: 0 txg: 0 pool_guid: 6503452912318286686 hostid: 4220169081 hostname: 'mini.home' top_guid: 18181370402585537036 guid: 17772452695039664796 vdev_tree: type: 'mirror' id: 0 guid: 18181370402585537036 whole_disk: 0 metaslab_array: 14 metaslab_shift: 30 ashift: 9 asize: 999856013312 children[0]: type: 'disk' id: 0 guid: 8869551029051110993 path: '/dev/da0p2' whole_disk: 0 DTL: 869 children[1]: type: 'disk' id: 1 guid: 17772452695039664796 path: '/dev/da2p2' whole_disk: 0 DTL: 868 create_txg: 0 (LABEL 1 - 3 identical) Thanks, Norbert ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
