Does btrfs still slow down the system until freezing, when doing snapshots of the sys subvolume? I never used btrfs again. Imagine, you set a cron for hourly snapshots, and what you get is 2 minutes of freezing every full hour 🙈 I never had that kind of trouble with other snapshotable file systems as sys volume.
This can happen when gquotas are enabled, thats why gquotas are not recommended with snapshots
I'll dig into that.
