[PATCH] xfstests: new check 276 to ensure btrfs backref integrity

2011-12-07 Thread Jan Schmidt
This is a btrfs specific scratch test checking the backref walker. It creates a file system with compressed and uncompressed data extents, picks files randomly and uses filefrag to get their extents. It then asks the btrfs utility (inspect-internal) to do the backref resolving from fs-logical

Cloning a Btrfs partition

I've got a 6TB btrfs array (two 3TB drives in a RAID 0). It's about 2/3 full and has lots of snapshots. I've written a script that runs through the snapshots and copies the data efficiently (rsync --inplace --no-whole-file) from the main 6TB array to a backup array, creating snapshots on the

Hello btrfs! Recently I upgraded to 3.2.0-rc4 due to instabilities with my btrfs filesystem in 3.1.1. While with 3.1.1 my system completely froze, with 3.2.0-rc4 it stays at least somehow usable (for some strange reason my xorg screen turns black as soon as this happens, only ssh is working
