Hi,

I'm trying to convert two ext4 FS to btrfs, but I'm surprised by the
time needed to do that conversion.

The first FS is on a 500GiB block device, and btrfs-convert is running
since more than 48h :
root      1978 25.6 47.7 748308 732556 ?       D    Feb18 944:44
btrfs-convert /dev/vg-backup/backup

The second is on a 340GiB block device, and the processing time is similar :
root     30192  5.2  3.0  73180 61520 pts/0    R    Feb18 121:04
btrfs-convert /dev/vg-balor/backup


Is it "normal", or is there a problem during the processing ?

Thanks,
Olivier

How much free space did those FS have? How many files were on them (was they 
dominated by small or large files)?
