similar to: global zone snapshots

Is there an existing RFE for, what I''ll wrongly call, "recursively visable snapshots"? That is, .zfs in directories other than the dataset root. Frankly, I don''t need it available in all directories, although it''d be nice, but I do have a need for making it visiable 1 dir down from the dataset root. The problem is that while ZFS and Zones work smoothly

Hi, I''d like to move a disk from one controller to another. This disk is part of a mirror in a zfs pool. How can one do this without having to export/import the pool or reboot the system? I tried taking it offline and online again, but then zpool says the disk is unavailable. Trying a zpool replace didn''t work because it complains that the "new" disk is part of a

What is a use case of setting a reservation on the base pool object? Say I have a pool of 3 100GB drives dynamic striped (pool size of 300GB), and I set the reservation to 200GB. I don''t see any commands that let me ever reduce a pool''s size, so how is the 200GB reservation used? Related question: is there a plan in the future to allow me to replace the 3 100GB drives with 2

Hello zfs-code, http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/uts/common/fs/zfs/vdev_cache.c 72 * All i/os smaller than zfs_vdev_cache_max will be turned into 73 * 1<<zfs_vdev_cache_bshift byte reads by the vdev_cache (aka software 74 * track buffer). At most zfs_vdev_cache_size bytes will be kept in each 75 * vdev''s vdev_cache. While it

Hello zfs-discuss, What would you rather propose for ZFS+ORACLE - zvols or just files from the performance standpoint? -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com

Hello I''m curious what is the best (if any) way to access ZFS snapshots from the non-global zones? I have a common ZFS file system (on Solaris Express b116 for ex.) in a global zone, mounted as lofs to several non-global zones. In each zone I can access all files with no problem, but I''m unable to the snapshots. I can get the list of snapshots, but not the content of

Hello zfs-discuss, I wonder if ZFS will be able to take any advantage of Niagara''s built-in crypto? -- Best regards, Robert Milkowski mailto:rmilkowski at task.gda.pl http://milek.blogspot.com

Hello zfs-discuss, Just to be sure - if I create ZFS filesystems on snv_39 and then later I would want just to import that pool on S10U2 - can I safely assume it will just work (I mean nothing new to on-disk format was added or changed in last few snv releases which is not going to be in u2)? I want to put right now (I have to do it now) some data on ZFS and later I want to

How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes). Thanks, -mg This message posted from opensolaris.org

Hello zfs-discuss, Relatively low traffic to the pool but sync takes too long to complete and other operations are also not that fast. Disks are on 3510 array. zil_disable=1. bash-3.00# ptime sync real 1:21.569 user 0.001 sys 0.027 During sync zpool iostat and vmstat look like: f3-1 504G 720G 370 859 995K 10.2M misc 20.6M 52.0G 0 0

Hi all. A quick question about the checksum error detection routines in ZFS. Surely ZFS can decide about checksum errors in a redundant environment but what about an non-redundant one? We connected a single RAID5 array to a v440 as a NFS server and while doing backups and the like we see the "zpool status -v" checksum error counters increment once in a while. Nevertheless the

Please can someone take a look at the attached file which shows the output on my machine of zfs list -r -t filesystem,snapshot -o space rpool/export/home/matt The USEDDS figure of ~2GB is what I would expect, and is the same figure reported by the Disk Usage Analyzer. Where is the remaining 13.8GB USEDSNAP figure coming from? If I total up the list of zfs-auto snapshots it adds up to about 4.8GB,

Hello, is there a way to add a zfs dataset to a zone online? The only info I found is to configure the dataset in the zone via zonecfg then reboot the zone. I would like to be able to add new separated dataset for each new db''s I add in the zone and of course if I need to reboot the zone every time I have to add/remove a db, my users will not be very happy... The only option I found

Hi zfs-discuss, I have some questions about throttling on ZFS 1) I know that throttling is activating while one sync is waiting for another. (http://blogs.sun.com/roller/page/roch?entry=the_dynamics_of_zfs) Is it possible to throttle only selected processes (e.g. nfsd) ? 2) How can I obtain some statistics about it? I want to know how often throttling is activating on my host etc. 3) Is it

I''m moving some data off an old machine to something reasonably new. Normally, the new machine performs better, but I have one case just now where the new system is terribly slow. Old machine - V880 (Solaris 8) with SVM raid-5: # ptime du -kds foo 15043722 foo real 6.955 user 0.964 sys 5.492 And now the new machine - T5140 (latest Solaris 10) with ZFS

I need to move data from one zpool to another, lock stock and barrel, Being from linux background my instinct was to use rsync. But then I remembered seeing the `export/import options in man zpool.. And I''ve seen mention of them here too, but didn''t pay attention since I''d noticed no need yet. Now I''m wondering if the export/import sub commands might not be

hi all, i''ve been using a SAN LUN as the sole member of a zpool with one additional zfs filesystem. this is a flat SAN fabric, so this LUN was available to other systems on the fabric, and one of them came up with "wrong magic number" for several drives, and, as best i can tell, the vtoc for my zpool LUN was over-written on that host via format labeling to correct the error.
