I have several Samba shares running on my Synology RackStation NAS server. Lets just call these Samba shares:
newton1 newton2 newton3
Each of the newtons is pointing towards a different RAID volume.
newton3 are working smoothly and accepting files in a timely way, as you would expect a Samba share to. But today I noticed that some users were having difficulty uploading files to
newton2 in particular.
On a Windows system; a user copied several files to
newton2; the names and file sizes appeared, but these files had no contents.
I tried replicating this on my Linux machine too via Thunar and had similar results.
(Note that this user and I have permissions to write in these files/directories I'm talking about.
user=rwx, group=rwx, other=rx)
touch test.txt directly on
newton2 and the file appeared, but when I tried editing the contents in Vim I got this error:
"test.txt" E667: Fsync failed
du . of
newton2 shows all of the recently uploaded files are null.
The RAID volume for
newton2 shows that only 6GB/30GB are used and the disks all appear healthy.
I'm really stumped at this point... Where do I go from here?
