Last time I was making a backup from my Desktop PC to my NAS, and suddenly after 10GB copied more or less Samba freezes and locks the filesystem. I thought it was a Samba issue so I switched to SCP (WinSCP) and same thing happened, filesystem locked (can't ls, cant stat any file, can't do anything on the specific folder that was target on the copy process). Due to lack of time and the fact that I had a spare 1TB external drive I ended up rsyncing everything from the external drive to my NAS, this process ended successfully after copying 200GB.
Anyway, today I reviewed some stats on the server and I found out that Wait I/O times are quite high. I don't know if this is common, or just a bug in the monitoring software, but got my attention obviously. I did an iotop and didn't find anything suspicious.
Maybe this issue is related to the filesystem locks, maybe not, but the NAS doesn't feel so stable.
