Hello, my NextCloud AIO installation has been running for three weeks. I have no problems, with the following exception: A Macrium Reflect backup cannot be opened.
The NextCloud datadir is on an ext4 drive. The Macrium backup is on the external NVME, but not in the NextCloud datadir. When calling the backup in Macrium, I get a general error. Three other Macrium backups on the same NVME do not cause any problems.
The "problematic" image has about 500GB, the others are much smaller. I have another copy of this image on an NTFS drive. This can be used in Macrium without any problems.
Now I wanted to simply copy the image from the NTFS to the external NVME, but I regularly get errors here.
No matter whether I make the copy via Windows, Cyberduck via WebDAV or with Rsync, it gets stuck at some point and there is no way to write to the NVME anymore.
After the failed copy attempt, the NVME seems to be in read-only mode, no files can be written (neither in NextCloud nor in the SMB-Share).
Rebooting omv settles the issue, the NVME works again (the Macrium image of course not)
While trying to copy the file, I got the following on the open putty session:
Message from syslogd@omv-nas at Apr 3 00:48:25 ...
kernel:[13857.795318] EXT4-fs (sdc1): failed to convert unwritten extents to written extents -- potential data loss! (inode 175243273, error -30)
Might this error <RE: NextCloud AIO - Permission denied?> be somehow related to the behavior described here?
Is there a problem with the NextCloud installation or the associated rights? Or do the signs point more in the direction of a hardware problem?
Thanks for your feedback!
