Can I backup nas config, take out disks, reset, restore backup and insert disk back to avoid data lo
My NAS keeps hanging after running for a while, day or days. I can't find any clue so plan to reset it, but I like to keep the data on the disks (raid5) If I take them out, backup config, res...
Thanks. That really helps.
The NAS is used for backup so it is easy to reset after copy data out. I put a new disk in for a week now and it runs well, so I guess it is a software issue. I will try to copy and reset today to save troubleshooting time.
May I know where to find full log? From the admin web portal I found logs of not much helpful details.

If you look at that log screen, you'll see a download control that will download the full zip file - which has a lot more info than you'll see on the screen.
I found that btrfs-transaction consumes almost 100% cpu time when I am rm some large files. Wil this be the reason that the system hangs?
Now the file deletion is completed, the process still consumes over 90% cpu. Btrfs quota is disabled.

How full is the data volume?
Do you have snapshots enabled? If so, are you using smart snapshots?
Have you looked at the log zip? Disk_info.log will give you some of the SMART stats. You can also look in system.log, kernel.log, and systemd-journal.log for btrfs and disk errors. Though you can also search the log directly from ssh with journalctl, and check the smart stats with smartctl -x
Less than half space is used.
Snapshot is not enabled, but it is used to store snapshots from main NAS
smartctl -x looks all good. 4th faulty disk is taken out.
I haven't read through journal, it takes too much effort to find root cause.
