Subject: Adding a 4TB disk to a 2x4TB btrfs (data:single) filesystem and balancing takes extremely long (over a month). Filesystem has been deduped with bees
Date: Fri, 1 Apr 2022 14:13:58 +0300 [thread overview]
Message-ID: <8a536fe1-68bd-4136-8cfb-bd410afc5fa1@gmail.com> (raw)
Hello,
I am running btrfs on 2x 4TB HDDs (data: single, metadata: raid1) and i
added another 4TB disk.
According to btrfs wiki i should run balance after adding the new device.
My problem is that this balance takes extremely long, it is running for
4 days and it still has 91% left.
Is this normal, and can i do anything to fix this?
kernel is linux-5.17.1, i have also tried with 5.16 kernels.
mount options are: rw,relatime,compress-force=zstd:11,space_cache=v2
I have been using bees for dedup, but it is disabled for the balance.
I am not doing any IO on the disks, they have no smart errors, and none
of them are SMR (2x WD40EFRX and 1x ST4000DM000)
Autodefrag is disabled, and i also have checked that the disks are in
stable drive cages in order to be sure i have no problems with vibration.
Benchmarking them gives normal speeds. Quotas have never been enabled.
