Linux no space left on device issue

Question

We have SUSE Linux OS:

$ uname -a Linux 3.0.13-0.27-default #1 SMP Wed Feb 15 13:33:49 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux 

Only for a specific file the file creation fails with error no space left on device. We are able to create other files, what has gone wrong? In the current scenario:

• Inode usage is only 47%

  $ df -i . Filesystem Inodes IUsed IFree IUse% Mounted on /dev/mapper/appvg-dsfs 39321600 18218000 21103600 47% /dsfs 

• Disk usage is only 82%

  $ df -h . Filesystem Size Used Avail Use% Mounted on /dev/mapper/appvg-dsfs 591G 457G 105G 82% /dsfs 

• File creation of one specific file fails in this case JDE_GL_INCR_STG_201504_181.log.load.058

  $ echo "a" > JDE_GL_INCR_STG_201504_181.log.load.058 -bash: JDE_GL_INCR_STG_201504_181.log.load.058: No space left on device echo "a" > testfile $ mv JDE_GL_INCR_STG_201504_181.log.load.058 tempfile mv: cannot stat `JDE_GL_INCR_STG_201504_181.log.load.058': No such file or directory 

• File creation of other files is possible

Answer 1

really do look like hash-collision issue. Have u tried creating this exact same file in any other empty directory on the same partition to test if it is really hash-collision issue or something else !!

Answer 2

I have seen issues of this nature when I have mounted a faulty or corrupted drive. If you have smartctl on the host, run it against the device (smartctl -a /dev/<device>). Different drives have different data, but look for things like: uncorrected errors, multi_zone_error_rate, current_pending_sector, raw_read_error_rate, or if it says the drive has failed. Those are all indicators that the is not in the best state.

Answer 3

Maybe you run out of Semaphores. Try this as root

ipcs -s 

and check if there are a lot of semaphores owned by the same user. If so run the following command

ipcs -s |grep username |awk '{print $2}' 

in the above command replace the username withn the actual user.

Answer 4

Firstly check the size of the file you are trying to create. The file might be very big. Ok I know the chances of the above being the issue may be low, rename the file to a different name or create it with different file name..
