And my disappointment in btrfs when it reminded me of how long it took to defrag a hard drive was limitless. 100 out of 500 GB used, free disk space 0, had to spend an afternoon running rebalance with various parameters to get to a point where it could run a full rebalance without running out of memory. Of course our IT seems to love it since it comes with all possible bells and whistles so I already dread the next time it happens.

Is this anecdotal of some years ago or recent? Are they running a really old kernel? btrfs had this sorts of problems, but some major fixes in this regard have been committed like two years ago.

The issue was earlier this year, but the systems I saw it on were probably both LTS with an older kernel.Good to know that it was fixed.

No probably no a old kernel....but i know like everyone btrfs...that never happened to me.
