Deleting large file fails and crashes NAS
Hi all.
I have a 300GB file that I want to delete however when I try to do it via Windows or SSH it fails and crashes the NAS, meaning I have to remove the power to reboot it (it doesn't respond to...
You could try a single truncation via ssh
truncate -s 0 myfile.ext
Progressive truncation just uses different parameters for -s (size). For instance, -s 100G or -s 100M.
Echo is another tool that can truncate a file.
echo > myfile.ext
Either way, turn snapshots off before you do this. Perhaps also disable checksums and quota if they are enabled (look on the volume settings wheel).
If it works, I suggest running a balance afterwards. If that also locks up, then post back.
I suggest running the disk test next - it's one of the options on the volume settings wheel.
Also, download the log zip, and see if there are any disk or BTRFS errors in system.log and kernel.log.
Running a disk text now. For a 4TB setup in RAID1 (4TBx2) how long should I expect this to take?
The last one I ran took 13 hours with a 4x6TB array with healthy disks. I'm not sure if it tests the drives sequentially or in parallel. Maybe assume about 8 hours.
If you have spindown enabled, maybe temporarily turn that off.
Thanks Stephen, will leave it going then! :) Have turned off disk spin down, had it set to 240 minutes inactivity.
No disk errors in kernel.log or system.log which is reassuring.
Only errors I see are these:

Looks like the disk test went through fine from the Logs section:
Thu May 3 2018 0:25:10 Volume: Disk test completed for volume data.
Wed May 2 2018 15:22:17 Volume: Disk test started for volume data.Overnight the admin panel closed so it closed I can't see the "Info, Warning, Errors" popup any more.
Unsure how I can get to this again or if I need to as the disk test completed (would it show any warnings or errors in Logs?)
I have not tried the a method to progressively delete huge files via SSH by repeatedly truncating it.
How would I go about doing this?
