It breaks something inside of influxdb2, which results in flurry of errors like these: > ts=2021-12-21T18:19:35.513910Z lvl=info msg="Write failed" log_id=0YZYwvV0000 service=storage-engine service=write shard=50 error="[shard 50] unlinkat ./L1-00000055.tsi: read-only file system" I believe this is somehow caused by a mount namespace that systemd creates for the service, but I didn't investigate this deeper.
