That sounds quite odd.

You should send the logs, so we can look at it.

Thanks for the suggestion. Log files sent. Regards.

I am going to check with someone to see if they are able to look at the logs to find the core issue. It sounds like there might be something with the file system.
Are you able to access your data okay?

Restart w/ a volume scan. LV looks fine as well as the RAID and dumpe2fs.
Maybe a filesystem check will correct it out.

Ok, I am now rebooting it and running scans ...
I did get an error message this morning when logging on to the web interface.
"ATA error count has increased in the last day. Disk 2: Previous count: 5 Current count: 6 Growinf SMART error indicate a disk that may fail soon. If the errors continue to increase, you should be prepared to replace the disk."

Ok, rebooting and scanning seems to have sorted the issue.

Many thanks for the suggestion.

May I ask another quick question ?
At the moment, I have 2 disk of 500 Go ...
Can you please confirm that if I want to expand the storage space, I have 2 solutions:
1- addind a third (or fourth, fifth ..) hard drive of the same capacity in order to expand storage space.
or
2- remove one of the 2 500Go disks - then add for exemple a 1To hd, wait for data to be copied ... reboot ReadyNas in order to expand free space, then replace the other 500Go disk leave by another one of 1To

Thanks

Basically yes. But not 100% right,
-With option 1, you could add 1 TB drives, you are not limited to 500 GB.
-With option 2, there is no expansion until you install the second 1 TB drive. With normal single-redundancy, the capacity of the array is the total minus the largest.

If you are happy with single redundancy, then it is cheaper (per GB) to fill the empty slots first. Of course that assumes your existing drives are not failing.

If you are considering dual redundancy in the future (ultra/pro supports this, not sure about nvx), then add a third 1TB drive, then after expansion completes replace one of the initial two with a second 1 TB drive. That leaves an empty slot for the future dual-redundancy drive

Only 6-bay or greater models support dual-redundancy.
