Hi list, i tried to write my first type and provider that should create logical volumes. Seems like i''m missing something as i get nothing when i use it: No errors and no logical volume :-( type/logicalvolume.rb: ================= Puppet::Type.newtype(:logicalvolume) do @doc = "Manage logical volumes" ensurable newparam(:lvname) do desc "The logcal

Just checking to be sure this isn''t a known bug or problem. I couldn''t find a bz for this, but it would appear that tunefs.lustre --print fails on a lustre mdt or ost device if mounted with mmp. Is this expected behavior? TIA mds1-gps:~ # tunefs.lustre --print /dev/mapper/mdt1 checking for existing Lustre data: not found tunefs.lustre FATAL: Device /dev/mapper/mdt1 has not

> If 3.9 shipped with these issues (assuming these are not false positive), it would be interesting to 1) know why the sanitizers didn’t catch it, and 2) add valgrind to the release qualification process (CC Hans). Yes, I'd be interested to see some corroboration. Note that the issue here is pretty specific: it only happens during optimized compile using Clang-3.9. This is all I did:

Hi All, the following patches implement the recursively snapshotting and deleting of a subvolume. To snapshot recursively you must pass the -R switch: # btrfs subvolume create sub1 Create subvolume ''./sub1'' # btrfs subvolume create sub1/sub2 Create subvolume ''sub1/sub2'' # btrfs subvolume snapshot -R sub1 sub1-snap Create a snapshot of

Hello all, in IRC we had a discussion on how we could solve sending live subvolumes and how to send subvolumes without the need to administrate/keep old snapshots for incremental sends. One of the ideas was to introduce "sendshots", which are basically snapshots where no refs are counted for file data. This means, that when file data is changed in the sendshot origin, we do not consume

Hello, This is the second attempt to bring in cross subvolume reflinks into btrfs. The first attempt was NAKed due to missing vfs mount checks and a clear description of what btrfs subvolumes are and probably also why cross subvolume reflinks are ok in the case of btrfs. This version of the patch comes from David and is in SUSE kernels since a long time, so it is tested and working. The patch

Hi all, I suffered a lot for the terrific performance of aptitude on a BTRFS filesystem. I don''t think that BTRFS is a slow filesystem, but it seems that some aptitude (or dpkg) patterns are capable to highlight the btrfs slowness in some corner case. In order to alleviate this problem, I wrote a small script which calls aptitude with the LD_PRELOAD libeatmyadata library. And now I

Hi A friend has a disk with an hfs filesystem on it; we'd like to move it to a Debian (etch 2.6.18-6) box and share it via samba 3.0.24. I can mount the hfs disk and see the files on the linux box : good I can share a normal (xfs/etx3) fs via samba to the Mac : good Although I can share the hfs fs via samba, the extended attributes are not visible; so the existing files on the hfs

Ok so the install has been seamless on a few machines and I decided to try it on my laptop (a Dell D620). I had everything working great and kicked it around a bit and then figured, if I'm going to keep this on my laptop I'll need to reformat everything, enable some encrypted filesystems etc ... not a big deal ... kind of Here's the problem, the laptop has a resolution of 1440x900 and

Hi, I wanted to create a new btrfs fs for my backups. When trying to mkfs.btrfs for that device, I''m getting "error checking /dev/loop2 mount status" With strace I see where the problem is: lstat("/dev/disk/by-id/ata-INTEL_SSDSA2M160G2GC_CVPO939201JX160AGN-par", 0x7fffa30b3cf0) = -1 ENOENT (No such file or directory) The problem is there is something missing

Hi Seto, please could you update also the man page too ? Why it was not provided a way to clear a *single* flag ? To me it seems a bit too long to clear all the flag (btrfs mount-option clear) and then set the right one. As user interface I suggest something like chmod: btrfs mount-option set +ssd,skip_balance -nodatacow /dev/sdX or btrfs mount-option set =ssd,skip_balance,nodatacow

Hello, yesterday I experienced following problem with my ext3 filesystem: - I had ext3 filesystem of the size of a few TB with journal. I correctly unmounted it and it was marked clean. - I then ran fsck.etx3 -f on it and it did not find any problem. - After increasing size of its LVM volume by 1.5 TB I resized the filesystem by resize2fs lvm_volume and it finished without problem. - But

Some new features in CVS HEAD are: - v1.0 saves most of the data to dovecot.index.cache only when the client is FETCHing the messages. With mboxes the message headers are saved while parsing the mbox, which is almost the same thing. With CVS HEAD the dovecot.index.cache file is updated already when the new messages are being saved (with deliver or IMAP APPEND). This avoids reading the message
