Hi.
Badblocks finished on both disks with no errors. The only messages from
kernel
during night are 6x perf: interrupt took too long (2511 > 2500),
lowering kernel.perf_event_max_sample_rate to 79500

(still used "old" version of btrfs tools, working remotely now, I will
boot something newer when I will get access to that NAS at EOD)
Thank you

Hello,
thank you for the reply.
What do you get for btrfs fi df /array
Can't do that because filesystem is not mountable. I will get stats for '/'
filesystem instead (because '/array' is an empty directory - mountpoint on /
Try
$ sudo btrfs-debug-tree -t chunk /dev/mapper/first | grep 'METADATA\|SYSTEM'
You need to adapt that /dev/ node for your case, I just copy pasted
that from my setup. Anyway, that will look at the chunk tree and show
the profile for these chunk types.
