mgutt Posted October 2, 2020 Share Posted October 2, 2020 (edited) My backup NAS was victim of a power outage and since it restarted, one disk shows errors and sometimes "Unmountable: No File System". As I'm only able to access it remotely through a VM I'm not able to stop the array. At first I tried to repair it: xfs_repair -v /dev/md6 xfs_repair: cannot open /dev/md6: Device or resource busy Then I unmounted it: umount /dev/md6 And repaired it again: xfs_repair -v /dev/md6 Phase 1 - find and verify superblock... superblock read failed, offset 0, size 524288, ag 0, rval -1 fatal error -- Input/output error Tried remounting: mount -t xfs /dev/sdg1 /mnt/disk6 mount: /mnt/disk6: special device /dev/sdg1 does not exist Checked all existing disks and it seems to be dead as sdg / sdg1 is missing completely: lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT loop0 7:0 0 9.1M 1 loop /lib/modules loop1 7:1 0 7.1M 1 loop /lib/firmware loop2 7:2 0 20G 0 loop /var/lib/docker loop3 7:3 0 1G 0 loop /etc/libvirt sda 8:0 1 14.2G 0 disk └─sda1 8:1 1 14.2G 0 part /boot sdb 8:16 0 12.8T 0 disk └─sdb1 8:17 0 12.8T 0 part sdc 8:32 0 12.8T 0 disk └─sdc1 8:33 0 12.8T 0 part sdd 8:48 0 12.8T 0 disk └─sdd1 8:49 0 12.8T 0 part sde 8:64 0 223.6G 0 disk └─sde1 8:65 0 223.6G 0 part /mnt/cache sdf 8:80 0 12.8T 0 disk └─sdf1 8:81 0 12.8T 0 part sdh 8:112 0 12.8T 0 disk └─sdh1 8:113 0 12.8T 0 part md1 9:1 0 12.8T 0 md /mnt/disk1 md2 9:2 0 12.8T 0 md /mnt/disk2 md3 9:3 0 12.8T 0 md /mnt/disk3 md4 9:4 0 12.8T 0 md /mnt/disk4 md5 9:5 0 12.8T 0 md /mnt/disk5 md6 9:6 0 12.8T 0 md Could I check something else? If not I would pick up the NAS in a few days and replace the disk and restore from backup. Edited October 2, 2020 by mgutt Quote Link to comment

trurl Posted October 2, 2020 Share Posted October 2, 2020 You must start the array in Maintenance mode to run repair. Don't see it in SMART though. Maybe try rebooting Quote Link to comment

My friend on the external location needed to hold the power button to reboot the server and finally after restart I'm in the same situation (not seeing the disk through terminal). Does anyone have an idea to accces the WebGUI remotely without starting the array (I'm not able to open ports on the remote side)? It's strange how the disk is listed (8.1 GB total size ^^): Edited October 2, 2020 by mgutt Quote Link to comment

The WebGUI comes up regardless of the array status, I log into my server and manually hit the start button normally. Quote Link to comment
mgutt Posted October 2, 2020 Author Share Posted October 2, 2020 Just now, jonathanm said: Not sure what you are getting at. This is my external backup NAS. Its located in an other city. I'm able to control it remotely through a Lubuntu VM + VNC Viewer (Real VNC). If I would stop the array, the VM would be killed and I loose the ability to access it. Quote Link to comment
trurl Posted October 2, 2020 Share Posted October 2, 2020 You should setup the builtin Wireguard. It works without the array started. Quote Link to comment

trurl Posted October 2, 2020 Share Posted October 2, 2020 Open port to your Unraid server, Wireguard clients on devices that need access Quote Link to comment
mgutt Posted October 2, 2020 Author Share Posted October 2, 2020 1 minute ago, trurl said: Open port to your Unraid server Not possible. It's not my router. Could the external NAS connect to my server as a client so it becomes part of my local network or are open ports on both sides a must? Quote Link to comment
trurl Posted October 2, 2020 Share Posted October 2, 2020 Never tried it any way where Unraid was not the one with the open port, clients don't need any. Maybe ask on the Wireguard thread. Quote Link to comment
