Strange issue - no GUI, some dockers up and running

[denisvic]

Hi all,

 

This morning I noticed some problems on my network (internet access up but DNS down). I use Adguard Home for my DNS.

UNRAID webgui is unresponsive but SSH yes. Some dockers work well (tailscale for example) some others don't work at all (unifi-controller, adguard, ...). I've tried to reboot server without a change. "My Servers" seems to work well but I didn't activate remote access. I've seen some bad words in syslog (attached).

 

 

Someone can help me to solve this weird issue ?

Could you help me generate diagnostics without webui (broken)

Click on the link.

My fault I haven't seen "diagnostics" command. I've sent you the file by PM (maybe with some private data)

[JorgeB]

You can post the anonymized diags, pleas post them here instead, this way other users can also help, I'm not always available.

There's filesystem corruption detected:

 

Jan  2 06:55:31 nas kernel: BTRFS critical (device nvme0n1p1): corrupt leaf: root=2 block=50997444608 slot=32, unexpected item end, have 2467418972 expect 14587

 

Suggest backing up then reformatting this fs.

It seems to refer to one disk (nvme) of my two-disk cache (1 x nvme and 1 x SATA SSD). Could you help me solve this issue ?

Can I simply remove the nvme disk (redundancy), format it (or replace if faulty) and "rebuild" the FS ?

 

Thank you for your help

This is a filesystem problem, not a device issue, in these cases I usually recommend backup and reformatting to avoid future issues, but if you want you can try a filesystem repair, but only after backing up all you can since it might make things worse.

I've backed up my data, how now can I format the cache without GUI ??

 

Thank you for your help

Disable array auto-start by editing disk.cfg on your flash drive (config/disk.cfg) and changing startArray="yes" to "no", then reboot and should have GUI access.
