Good morning Btrfs list, I have been loading a btrfs file system via a script rsyncing data files from an nfs mounted directory. The script runs well but after several days (moving about 10TB) rsync reports that it is sending the file list but stops moving data because btrfs balks saying too many files open. A simple umount/mount fixes the problem. What am I flushing when I remount that

Glück Auf! I use now kernel 3.2. The filesystem was originally created under 2.6.39 on 1 whole hdd, mounted with "noatime,nodiratime,inode_cache". I use it for backups: rsync the whole system to a subvolume, snapshot it and then delete some tempfiles in the snapshot, which are 90% of the full-backup, all once a day. In figures: on this 1 TB hdd is the full-backup with around 600 GiB and

What are the recommendations for running KVM images on BTRFS systems using kernel 3.4?  I saw older posts on the web complaining about poor performance, but I know a lot of work has gone into btrfs since then.  There also seemed to be the nocow option, but I didn''t find anything that said it actualy helped. Anybody have ideas? Thanks, Matt -- To unsubscribe from this list: send the line

Hello, is it possible to set nodatacow on a per-file basis? I couldn''t find anything. If not, wouldn''t that be a great feature to get around the performance issues with VM and database storage? Of course cloning should still cause COW. Thanks, Ralf-Peter -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

Hello list, i know what btrfs don''t support swap files. I read arch wiki and when i reading about systemd addon for auto create swapfile on btrfs, i invent the way, how create and using swap file, just see following sh code: swapfile=$(losetup -f) #free loop device truncate -s 8G /swap #create 8G sparse swap file losetup $swapfile /swap #mount file to loop mkswap $swapfile swapon

Hi. I''m considering an imminent switch from ext4 to btrfs and I''m hoping that someone can lend me advice before I do something unsupported. I have a software raid 6 array configured via mdadm. It was sitting at 8 x 3TB until I recently doubled that, grew the array and found that ext4 doesn''t want to resize. So, I''m looking to: 1. convert from ext4 to btrfs

Hello, I have a filesystem that has become unusable because of a balance I can''t stop. It is very close to full, and the balance is preventing me from growing it. It was started like this: sudo btrfs filesystem balance start -v -musage=60 -dusage=60 /srv/backups It has been stuck at 0% across reboots and kernel upgrades (currently on 3.8.1), and cancelling it had no effect: Balance

Hello. I've been experimenting with the USB connection of an Ippon BackComfoPro 800. This is the device "06da:0003 Phoenixtec Power Co., Ltd". The current SVN version of NUT does not work with this device. The megatec_usb driver can't get a proper reply to a Q1 request, failing with an error message about "short read (14 bytes)" instead. I have found the reason for

Hi! With 3.2-rc4 (probably earlier), Ext4 seems to remember what areas it trimmed: merkaba:~> fstrim -v /boot /boot: 224657408 bytes were trimmed merkaba:~> fstrim -v /boot /boot: 0 bytes were trimmed But BTRFS does not: merkaba:~> fstrim -v / /: 4431613952 bytes were trimmed merkaba:~> fstrim -v / /: 4341846016 bytes were trimmed Is it planned to add this feature to BTRFS

Hi, I have 4 machines, all converted to BTRFS about 6 months ago, now all running Ubuntu Quantal with kernel 3.5.0-17 The matter is that all these machines are now getting slower and slower everyday, every disk access causing the disk to be 100% busy for long periods, to the point that I''m now seriously considering migrating everything back to ext4...

Hello, (this is a recap of yesterday''s discussion on BTRFS IRC, also to save relevant pastes before pastebins expire) I have my /home on btrfs; a cronjob makes one snapshot every 30 minutes; these snapshots are kept for 24-48 hours, then deleted in batches. This is a 16K Leaf/Node BTRFS on top of mdadm RAID1. As system uptime approached 2 weeks, I started noticing that the free space

sorry forgot to follow the protocol, now included RFC in the subject. Hi, Appears that no one is working on the auto-snapshot feature for btrfs, so here I am implementing the same. Below is a draft on the feature list. Any comments / questions / suggestions are welcome, please do let me know. btrfs auto snapshot feature will include: Initially: - configurable timely

NOTE: in order to apply this patch you should: git mv btrfsck.c cmd-fsck.c This patch moves btrfsck in to "btrfs fsck". It also adds support for symlinks to the btrfs binary to retain compablity, =) I think something should be done to the help description but i''m not sure what... Anyway, feedback is welcome. -- To unsubscribe from this list: send the line "unsubscribe
