OpenVMS system disk FULL

smsc_1 — Mon, 08 Oct 2018 17:12:13 GMT

Hello community, I have a problem with OVMS system disk, I tried to search files greater then 50000 blocks, and delete them, but I'm still at 2% free.

DIRECTORY /SELECT=SIZE=MIN=50000 SYS$SYSDEVICE:[*...]

Device          Volume Label    Used Blocks     Free Blocks   Tot/Blks
------------ ------------     -------------     -------------    --------
DSA0:         IA64VMSSYS     282434976 (98%)     4314512 ( 2%)   286749488

I really don't understand which is the directory or files who occupied such spaces.

Could you please help to free up space??

Thank you

Lucas

   You don't need large files to fill a disk; many small files will do
the job just as well (if not better).

   I don't know if some existing tool would help with this, but a small
DCL script might be useful:

ITS $ type dirsiz.com
$!                                              2018-10-08 SMS.
$! DIRE /GRAND for all directories in P1
$! Default: sys$sysdevice:[000000]
$!
$ dir0 = p1                                     ! Top dir.
$ if (dir0 .eqs. "")
$ then
$    dir0 = "sys$sysdevice:[000000]"            ! Default P1.
$ endif
$!
$ top:
$    dir = f$search( dir0+ "*.dir")             ! Next directory.
$    if (dir .eqs. "") then goto bot            ! Done.
$    dir1 = f$parse( dir, , , "name")           ! Ignore "[000000]"
$    if (dir1 .nes. "000000")
$    then
$       dirs = dir0- "]"+ "."+ dir1+ "...]"     ! Form subdir spec.
$       write sys$output "--------"             ! Spacer.
$       write sys$output dirs                   ! Show subdir spec.
$       dire /size = allo /grand 'dirs'         ! DIRE command.
$    endif
$    goto top                                   ! Loop.
$ bot:
$!

   If that script finds a big directory, then you could re-run it,
specifying the big directory:

      @ dirsiz.com sys$sysdevice:[ANONYMOUS]

Thank you Steven, your script is great!!!

After long analysis I discovered the directory/file who filled the disk:

Directory SYS$SYSDEVICE:[000000.SYS0.SYSCOMMON.HP.NODES.SMWIZ2.SVCTOOLS.SPECIFIC.WEBES.LOGS]

DESTA_DIR.LOG;2               File ID: (25842,1746,0)
Size:    227971719/227982384 Owner:    [SYSTEM]

Total of 1 file, 227971719/227982384 blocks.

I deleted this file (it was old log file) and now I got all the space:

Device          Volume Label    Used Blocks     Free Blocks   Tot/Blks
------------ ------------     -------------     -------------    --------
DSA0:         IA64VMSSYS      45387232 (15%)   241362256 ( 85%)   286749488

I don't know why this old file take so much space, it was impossible to analyze it, anyway the newer version seems ok.

Thank you very much!
