.... I can register my function so it will be called when there are memory problems, which I do. I using it for ARC layer. Even with this in place under heavy load the kernel panics, because memory with KM_SLEEP cannot be allocated. Here are some statistics of memory usage when the panic occurs: zfs_znode_cache: 356 * 11547 = 4110732 bytes zil_lwb_cache: 176 * 43 = 7568 bytes arc_buf_t: 20 * 7060 = 141200 bytes arc_buf_hdr_t: 188 * 7060 = 1327280 bytes dnode_t: 756 * 162311 = 122707116 bytes !! dmu_buf_impl_t: 332 * 18649 = 6191468 other: 14432256 bytes (regular kmem_al...

In place of padding in zfs znode i added a new field. stored an integer value and am able to see saved information. but after reboot it is not there. If i was able to access before reboot so it must be in memory. I think i need to save it to disk. how does one force zfs znode to disk. right now i dont do anything special for i...

i need to get inodeno on ZFS and i am not able to find how to find it in kernel at vfs layer. i have vnode pointer and i am doing VTOZ to get znode but printing z_id from znode pointer gives me deadbeef(unitialized) , can somebody point me how to get that? i looked at zfs_getattr code and it does similar thing which i am doing but its able to get me inode no in getattribute structure(node id), that makes me thinking there is something mor...

Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return the znode anyway, otherwise an open() followed by an unli...

In my testing, I''ve found the following error: zpool status -v pool: local state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: none requested

I managed to create a link in a ZFS directory that I can''t remove. Session as follows: # ls bayes.lock.router.3981 bayes_journal user_prefs # ls -li bayes.lock.router.3981 bayes.lock.router.3981: No such file or directory # ls bayes.lock.router.3981 bayes_journal user_prefs # /usr/sbin/unlink bayes.lock.router.3981 unlink: No such file or directory # find . -print

Hi matt, I have some problems about understanding zfs COW implemention. Suppose b and c are both children dir of a, if c changes, there will be new versions of both a and c, namely c'' and a''. a a'' b c c'' Because ''..'' in b points to a before this change, shall we modify b to let ''..'' point to a''? If yes,

Hi I''m looking into forensic aspects of ZFS, in particular ways to use ZFS tools to investigate ZFS file systems without writing to the pools. I''m working on a test suite of file system images within VTOC partitions. At the moment, these only have 1 file system per pool per VTOC partition for simplicity''s sake, and I''m using Solaris 10 6/06, which may not

I''m seeing some pretty pitiful performance using ZFS on a NFS server, with a ZFS volume exported (only with rw=host.foo.com,root=host.foo.com opts) and mounted on a Linux host running kernel 2.4.31. This linux kernel I''m working with is limited in that I can only do NFSv2 mounts... irregardless of that aspect, I''m sure something''s amiss. I mounted the zfs-based

Adam, With the blog entry[1] you''ve made about gzip for ZFS, it raises a couple of questions... 1) It would appear that a ZFS filesystem can support files of varying compression algorithm. If a file is compressed using method A but method B is now active, if I truncate the file and rewrite it, is A or B used? 2) The question of whether or not to use bzip2 was raised in the

I have a huge problem with space maps on thumper. Space maps takes over 3GB and write operations generates massive read operations. Before every spa sync phase zfs reads space maps from disk. I decided to turn on compression for pool ( only for pool, not filesystems ) and it helps. Now space maps, intent log, spa history are compressed. Not I''m thinking about disabling checksums. All

Would it be worthwhile to implement heuristics to auto-tune ''recordsize'', or would that not be worth the effort? -- Regards, Jeremy

Hello all, I have an oi_148a PC with a single root disk, and since recently it fails to boot - hangs after the copyright message whenever I use any of my GRUB menu options. Booting with an oi_148a LiveUSB I had around since installation, I ran some zdb traversals over the rpool and zpool import attempts. The imports fail by running the kernel out of RAM (as recently discussed in the list with
