I have very strange problem that I don't know how to debug further. Drive is WD 2TB. I use it only for backup of my cloud and server data (lot of small files).
I'm using linux and dm-crypt.. whole disk is without partition and entirely crypted. I mount it using mount /dev/mapper/crypt ./folder/.
this is my current state with
Filesystem Size Used Avail Use% Mounted on .... /dev/mapper/crypt 1.9T 972G 891G 53% /BACKUP
rsync just told me there is no more space on drive.
du -sh /BACKUP/ is confirming space:
du -sh /BACKUP/ 972G /BACKUP/
Yes, I unmounted forced fsck, even tried to shrink filesystem and all. Plus + what is most discomforting is that I did
cat /dev/urandom >> ddd.dd
and it filled whole drive .. 100% .. I deleted some files prior to that. As if it shows full I cannot, it's full.
Some kind of filesystem limit or?
UPDATE: I cannot add or create files when it says it's full. But if I delete any small file i can create file of any size, for example:
ls /BACKUP/GDRIVE/10\ SHORT\ SIGHTED.mp4 -Alh -rw-r--r-- 1 root root 12M Aug 1 2015 /BACKUP/*******/10 SHORT SIGHTED.mp4 rm /BACKUP/GDRIVE/10\ SHORT\ SIGHTED.mp4 echo ddd > dd.dd cat /dev/urandom >> ddd.dd -bash: ddd.dd: No space left on device cat /dev/urandom >> dd.dd ^C #:/BACKUP# ls -Alh total 2.8G -rw-r--r-- 1 root root 2.8G Mar 5 14:14 dd.dd drwxr-xr-x 34 root root 4.0K Mar 5 14:12 ******* drwxr-xr-x 30 root nogroup 4.0K Feb 25 15:22 ******* drwx------ 2 root root 16K Sep 19 16:03 lost+found drwxr-xr-x 5 root root 4.0K Dec 27 03:09 ******* drwxr-xr-x 28 root root 4.0K Jan 2 18:48 *******
