Deleted an account used for TimeMachine and my RN is now in ReadOnly Mode...

Same problem here, last tuesday I deleted an account used for Time Machine only (1TB reseved) and then I couldn't connect via AFP, I managed to connect with samba and then I found that the filesystem was read-only... At least I could copy almost everything, bit by bit because if I tried to copy a big amount of data the NAS hang and the only way to restart it is unplug the power...

My firmware was 6.9.2, there are 4 HD WD-Red 2TB, in raid5 configuration. It has been running since 2015

# mdadm -D /dev/md127
/dev/md127:
Version : 1.2
Creation Time : Sat May 9 10:28:11 2015
Raid Level : raid5
Array Size : 5845988352 (5575.17 GiB 5986.29 GB)
Used Dev Size : 1948662784 (1858.39 GiB 1995.43 GB)
Raid Devices : 4
Total Devices : 4
Persistence : Superblock is persistent

I tried everything, frome the web interface and ssh (test data, scrub, delete cache, repair...). repair always abort.

Updated to 6.10.2 hoping that repair will work but same situation...

The hard disks look OK, I ran smartctl -a -d sat in each of them, no errors and there was a extend test maybe triggered by one of the actions I took from the web interface.

SMART Self-test log structure revision number 1
Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error
# 1 Extended offline Completed without error 00% 30866 -

So the hardware doesn't seem the problem.

I have been using ReadyNAS for more than 10 years, I have 5 of them now... I won't delete any time machine back up in the future and I will use my owns linux system witn XFS for storage....
