OS: Tru64 5.1B with Patch 4 running on DS20E
The "vdump" output prints these lines and there is no further progress. The "Compression" and "Tape in Use" lights on the tape drive are constantly ON. The light on the hard drive is continuously ON.
prg_root#> /sbin/vdump -N -v -0 -u -f /dev/ntape/tape0_d1 /users
path : /users
dev/fset : users_dmn#users
type : advfs
advfs id : 0x3e42ab82.000cac70.1
vdump: Date of last level 0 dump: the start of the epoch
vdump: Dumping directories
-----------------------------------------------
prg_root#> file /dev/ntape/tape0_d1
/dev/ntape/tape0_d1: character special (19/121) SCSI #1 "DLT8000" tape #6 (SCSI ID #0) (SCSI LUN #6)
The disk (/users) has the following sizes:
Drive (disk1c) size = 17782536 K
Drive used size = 12323700 K (71% full)
As a final note, I can successfully backup my other disk drives (/, /usr, etc.) to the same tape device using the same "vdump" command. As an alternate method, I am using "tar" to backup this drive and there are no errors.
Why is "vdump" not completing its task for this particular drive ? Any pointers will be appreciated.
Regards...

SolutionDid you check binary.errlog for errors on dsk1 ?
Although the symptoms are not the same you could try the vdump patch for patchkit#4, see:

Re: vdump not completing the task in 5.1B
how long have you waited for vdump to complete?
Have you checked the drive with dd?
greetings,
Michael

Re: vdump not completing the task in 5.1B
Michael, I haven't checked the drive using 'dd' command. I suppose the command is:
"dd if=/dev/ntape/tape0_d1 of=foo ibs=800 cbs=80 conv=ascii". If not correct, let me know.
The server is off-site and I will get back with the output from 'dd' soon.
Regards...

Re: vdump not completing the task in 5.1B
This looks like a known problem to me.
Pl. confirm that vdump memory usage is very
high (~ 80%) of available memory on the m/c, when you see this problem.
In V51b pk4, vdump on a file system with over 100K files either fails with "Not enough memory to generate link table" or is exteremly slow due to very high memory usage.
Pl. refer to
http://www.itrc.hp.com/service/patch/patchDetail.do?patchid=T64KIT0024267-V51BB25-E-20041122
For the ERP.
Hope this helps.
Regards,
Srinivas.
