Are you using snapshots? qgroups (which you have to enable to see snapshot space utilization)?. I've had bad experiences with them on btrfs.

Are you using snapshots? qgroups (which you have to enable to see snapshot space utilization)?. I've had bad experiences with them on btrfs.
- Lex-2008 6y agonot OP, but using btrfs for 0.5 year with snapshots, snapper (which creates snapshots every hour) on NVMe under Arch. Haven't noticed any issues yet - qgroups are disabled, and snapper config decreased to have no more than 20 snapshots.
- codys 6y agoYa, I was using snapper but didn't restrict the number of snapshots so I probably had more than 20 I use zfs now and have many, many, more than 20 snapshots without issue. I wasn't using a nvme drive with btrfs, it was a sata ssd. So perhaps the higher io ops or lower latency also helps.
