I'm running OMV 2.2.1 on an Odroid XU4. The system is installed on the SDCARD, and I use an external hard-drive (USB2, 500GO) as storage. The system is idle most of the time, I generally use it to listen to music or watch movies in the evening.
It runs perfectly for 4-5 weeks, except that I notice that, since 1-2 weeks, the storage filesystem is remounted in read-only mode every 2 days.
It happened today, here is the relevant output from dmesg:
In order to bring the filesystem back in write mode, I need to unmount it, run fsck.ext4. Then, when it is remounted, it is accessible in write mode... until the next time it is remounted in readonly mode...
I know that there are a lot of chances that my disk is dying, but... how can I diagnose it?
After the fsck, the hard drive works correctly, I can write big files at good speeds and they do not seem to be corrupted.
Is there any other reason for this kind of errors?
