[LTP] No space left on device

[LTP] No space left on device

[Xiuzhe Xiao]

Hi

I met a problem when using LTP
Many tests failed because of "errno=ENOSPC(28): No space left on device"
Here is one of the example:

<<<test_start>>>
tag=readv01 stime=1518724492
cmdline="readv01"
contacts=""
analysis=exit
<<<test_output>>>
incrementing stop
readv01     1  TBROK  :  safe_macros.c:440: readv01.c:113: write(6,0x30274,4294967295) failed: errno=ENOSPC(28): No space left on device
readv01     2  TBROK  :  safe_macros.c:440: Remaining cases broken
<<<execution_status>>>
initiation_status="ok"
duration=0 termination_type=exited termination_id=2 corefile=no
cutime=0 cstime=1
<<<test_end>>>
INFO: ltp-pan reported some tests FAIL
LTP Version: 20170116
./runltp: line 973: cannot create temp file for here-document: No space left on device

root@adzs-sc589-ezlite:/opt/ltp# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/root              7462604    555564   6504916   8% /
devtmpfs                110608         0    110608   0% /dev
tmpfs                   110688        40    110648   0% /run
tmpfs                   110688        52    110636   0% /var/volatile

Notice I have plenty of space on my disk, and I also check "df -i". Inodes are free as well
Is anyone had this problem? Please give me a hint, I'll be appreciated

I have never seen such failure.

But if you look at the the actual error message it looks like something
very wrong is happening there. The test is supposed to write 64 bytes to
the temporary file but it looks like in your case it attempts to write
4294967295 bytes, which is around 4GB if I'm counting correctly so it's
no wonder it fails with ENOSPC.

My guess is that the test is miscompiled somehow but that is just a wild
guess.

[LTP] No space left on device

[Xiuzhe Xiao]

Hi


I fixed this problem by adding option "-b" and -"B"

the command looks like this: /opt/ltp/runltp -b /dev/loop0 -B ext4 -s readv01
