Can you explain what the difference in bytes mean, he thinks
he has a problem.
he vdumped the filesystem to another disk, and
said he got the same result.
vdump to tape, vrestore from tape.
So, suspect it is how he vdump handles certain
files.
However, he has other 3.x systems, which
do not do this, including same
type of usr_domain#usr filesystems.
this is his 4.0a filesystems....
he has not installed patches, but didnt see vdump/vrestore there,
may be oversight on my part.

| 1048.1 | Was he dumping a Clone or Live fileset? | DECWET::MARIER | Wed Apr 23 1997 10:33 | 2 | |
If he was dumping a live fileset, my guess would be that files were deleted/changed while vdump was being run. | |||||
| 1048.2 | Says both single-user and multi-user vdumps | NNTPD::"[email protected]" | decatl::johnson | Wed Apr 23 1997 11:28 | 31 |
He says that he has this in single-usr, and multi-user on both the original system disk and the vdumped system disk. I requested the output from a single-user dump. will re-stress this fact. Additional info: it was a 4.0 system, but found in messages this message which maybe revelent? could the "chk_bf_quota: user/group underflow" message have any Apr 18 20:52:28 esp vmunix: ADVFS: using 567 buffers containing 4.42 megabytes of memory Apr 18 20:52:28 esp vmunix: chk_bf_quota: user/group underflow Apr 18 20:52:42 esp vmunix: chk_bf_quota: user/group underflow Apr 18 20:56:59 esp vmunix: Alpha boot: available memory from 0x86a000 to 0x3ffe000 Apr 18 20:56:59 esp vmunix: Digital UNIX V4.0 (Rev. 386); Thu Feb 20 11:36:55 EST 1997 Apr 18 20:56:59 esp vmunix: Firmware revision: 6.1 Apr 18 20:56:59 esp vmunix: PALcode: OSF version 1.46 [Posted by WWW Notes gateway] | |||||

You need a patched quotacheck as it has a bug in V4.0*...Charlie Franks has the patch. You should enable QUOTA_CONFIG "yes" in /etc/rc.config, so that quotacheck is run automatically on reboot. It may be this that is causing the calculation problems, but I'm not sure. > >Apr 18 20:52:28 esp vmunix: ADVFS: using 567 buffers containing > 4.42 megabytes of memory >Apr 18 20:52:28 esp vmunix: chk_bf_quota: user/group underflow >Apr 18 20:52:42 esp vmunix: chk_bf_quota: user/group underflow >Apr 18 20:56:59 esp vmunix: Alpha boot: available memory from > 0x86a000 to 0x3ffe000 >Apr 18 20:56:59 esp vmunix: Digital UNIX V4.0 (Rev. 386); > Thu Feb 20 11:36:55 EST 1997 > >Apr 18 20:56:59 esp vmunix: Firmware revision: 6.1 >Apr 18 20:56:59 esp vmunix: PALcode: OSF version 1.46 > >[Posted by WWW Notes gateway] | |||||
