I use OpenMediaVault server v3.0.99 (Erasmus) with Snapraid plugin for OpenMediaVault v3.7.3 installed (using snapraid v11.2 ). Debian GNU/Linux v8.10 (jessie).
Using union filesystems plugin for OpenMediaVault v3.1.17 to merge the 4 data disks.
Using 500GB to 1000GB hdds 4 data, 2 parity (aka RAID6 mode).
Parity drives are both 1000 GB.
All data drives have at least 9 Gb free space.
I execute
snapraid sync
then stops with the following error:
1%, 13808 MB, 107 MB/s, CPU 13%, 2:04 ETA

Error writing the content file '/srv/dev-disk-by-label-SR3D3/snapraid.content.tmp' in sync(). Input/output error.
I can not find anything about it on Google.
Any idea how to fix it?
