Hi, I''ve been using btrfs for a while now, I''ve been utilizing snapshotting nightly/weekly/monthly. During the weekly I also do a backup of the filesystem to an ext4 filesystem. My storage is a linux md raid 5 volume. I''ve recently noticed these errors in the logs during the backup of the files to the ext4 filesystem. I am running RHEL 6.1 (2.6.32-131.0.15.el6.x86_64) I''d like to help in any way I can so I thought I''d post here to see if there is anything I can do to help.

I figured that would be the case but still thought maybe it could possibly be somewhat useful. I will give the newer kernel a try... BTW is nfs export "supported" yet? Thanks, Mike BTW Awesome work on btrfs it''s fantastic, it''s saved my household so many times when my wife has accidently deleted a ton of photos... -----Original Message----- From: Fajar A.
