[Gimle-users] Full file systems

[Kent Engström]

Dear Gimle Users,

some of the Accumulus Lustre filesystems mounted on
Gimle (and Vagn) are very, very full:

  Size  Used Avail Use% Mounted on
  6.8T  6.4T   13G 100% /nobackup/smhid4
   17T   16T  8.7G 100% /nobackup/smhid6
   90T   89T  153G 100% /nobackup/smhid7
  161T  157T  2.5T  99% /nobackup/rossby14
  8.2T  8.1T  153G  99% /nobackup/smhid5
   72T   69T  2.1T  98% /nobackup/smhid8

On smhid6, we are at a point were an automated test we run each night to
verify that the filesystem is OK fails because there is no space for the
test files. It is likely that you will get similar errors if you try
to write to the filesystem.

Please check if there is data you can delete, compress or move to a
newer /nobackup filsystem (such as smhid9 or rossby15).

If you are going to move large amounts of data, we recommend that you do
it on a compute node allocated using "interactive -N1" (to get good
performance without affecting other login node users), and that you use
rsync to copy the data, verify that it looks good at the destination,
and then delete it from the source. Feel free to contact
smhi-support at nsc.liu.se if you have questions.


Sincerely,
