similar to: adding new bricks for volume expansion with 3.0.x?

Hi Is there clean way to ensure that a glusterfs mount point specified in /etc/fstab is mounted automatically on boot under debian lenny when referencing a remote node for the volfile? In my test case everytime I reboot, the system tries to mount the filesystem before the backend 10ge interface comes up so it gets a "No route to host" and immediately aborts. I know I can dump a mount

Two files in the different subvolumes may have the same inode id, so The rb-tree which is used to manage the defragment object must take it into account. This patch fix this problem.

Hey folks, Does anybody know if any of these are on the roadmap for ZFS, or have any idea how long it''s likely to be before we see them (we''re in no rush - late 2008 would be fine with us, but it would be nice to know they''re being worked on)? I''ve seen many people ask for the ability to expand a raid-z pool by adding devices. I''m wondering if it

Hi, first of all, apologies if this isn't the right mailing list but it was the best I could find. If you know a better mailing list, please tell me. Today I tried to defrag one of my filesystems. It's a 3.5T large filesystem that has 6 software-raids in the bottom and then merged together using lvm. I was running ext3 but removed the journal flag with thor:~# tune2fs -O ^has_journal

Hello everybody, reading about the speed improvements possible with (on boot) preloaded files (which should be continuous on disk) I searched for a ext3 defrag program. I found an ext2 defrag program (http://www.ibiblio.org/pub/Linux/system/filesystems/defrag-0.70.tar.gz, available in debian as defrag) which would have an optimal feature (moving files by a list) but refuses to work on ext3.

This fixes three issues on move extents ioctl without auto defrag: a) In ocfs2_find_victim_alloc_group(), we have to convert bits to block first in case of global bitmap. b) In ocfs2_probe_alloc_group(), when finding enough bits in block group bitmap, we have to back off move_len to start pos as well, otherwise it may corrupt filesystem. c) In ocfs2_ioctl_move_extents(), set me_threshold both for

Hi, all, I got machines running continuously for long time, but then the underlying ext3 file systems becomes quite heavily fragmented (94% non-contiguous). We just don't have a chance to shutdown the machines since they are always busy.. I tried the defrag 0.70 version comes with e2fsprog package and standalone 0.73 packages, but neither help me since the defrag tool can not handle ext3.

Well, well, well, what can i do to repair my windows98 system now ? It still works relatively OK, but some applications do not, and it crashes more than usual. One more question is: can i run the defrag utility under windows without getting all the files mixed up? I had to reinstall linux after running defrag under windows because the nodes were all mixed up. Oh, by the way, before i get

I found this thread from a few months ago that seems to have been started by someone with the same problem I have, but it was not resolved: https://www.redhat.com/archives/ext3-users/2005-March/msg00000.html I have been trying to speed up my boot times and I notice that a lot of time is spent waiting on IO. Even with readahead-list precacheing files, it is reading at less than 1/4 of my

This commit fixes three issues on non-auto defrag path (defragfs.ocfs2 doesn't set OCFS2_MOVE_EXT_FL_AUTO_DEFRAG on range.me_flags): - For ocfs2_find_victim_alloc_group(), old code forgot enlarge bitmap range for global_bitmap case. Old code could generate negative vict_bit. - For ocfs2_probe_alloc_group(), old code forgot back off move_len when finding enough bitmap space. Old code has

Hi all, Fewer days ago a CentOS box server suffered a manual and unexpected reset (too large to explain: there are silly people in everywhere). The result was the system did not mount de root (/) partition and the boot process was stopped. I repair it easily: boot from LiveCD (Knoppix in my case), umount root partition and pass the e2fsck utility. Because of that I've used several fs tools

- Add incompat flag, otherwise btrfs-progs will report error when operating on btrfs filesystems mounted with lzo option. - Allow to turn on lzo compression for defrag operation: # btrfs filesystem defragment -c[zlib, lzo] <file> Note: "-c zlib" will fail, because that''s how getopt() works for optional arguments.

While exploring some btrfs maintenance with respect to defragmenting I ran the following commands: # filefrag /path/to/34G.file /path/to/5.7G.file /path/to/34G.file: 2406 extents found /path/to/5.7G.file: 572 extents found Thinking those mostly static files could be less fragmented I ran: # btrfs filesystem defragment -c /path/to/34G.file # btrfs filesystem defragment -c /path/to/5.7G.file and

I noticed that btrfs fi defrag -c<method> can''t be used to compress files unless they are fragmented. This patch corrects the problem, by informing should_defrag_range if compression is enabled, and skipping tests for extent and adjacent extents if it is.

Kernel 3.1-rc8 btrfs-progs-0.19 mount options: noatime,autodefrag (space_cache is enabled) There are snapshots present on the filesystem. When I do a btrfs fi defrag on a file, the file becomes much more fragmented. The end result can be a file with 20k times more fragments than before. Initially I thought the extents were just smaller but were next to each other, so I checked with both

Hi folks, I''m using Ubuntu 12.10 Quantal with # uname -r 3.5.0-24-generic And it seems I cannot defrag : # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found # btrfs filesystem defrag /boot/initrd.img-3.5.0-24-generic # echo $? 20 # filefrag /boot/initrd.img-3.5.0-24-generic /boot/initrd.img-3.5.0-24-generic: 3 extents found Any clue
