Veritas Volume Manager: Volume doesn't create "rdsk" entry

Veritas Volume Manager: Volume doesn't create "rdsk" entry

Post by *NO - SPAM*cosm » Mon, 27 Apr 1998 04:00:00



Unixware 2.1.2,  Veritas Volume Manager 2.1.1 (ODM) , SCO patch ptf3138c
has been applied

I've created a new disk group named "dskgrp2" and am trying to create a
volume.

Within the graphical volume manager, I create a sub-disk, then a plex,
then a volume.  The command which is run to create the volume (as shown
in the "Command Info Window") is:

    vxmake -U fsgen -g dskgrp2 vol my-vol  read_pol=SELECT user=cosmo
group=leads mode=0644 log_type=NONE len=1024000 plex=my-plex

The Command Info Window indicates that the command terminated normally.
However, there is no entry made into the directory
"/dev/vx/rdsk/diskgroup2" !

However, I *can* run the same sequence of steps, creating a new volume
in the "rootdg" disk group, the same `vxmake` command gets run, and an
entry is created in "/dev/vx/rdsk/rootdg", as it should be.

I also tried running the `vxmake` command from the shell, as root, and
the same thing happens (or doesn't happen).  `vxmake` exits with a zero
status, indicating no error at all, but no rdsk entry is created.

Any ideas???  TIA.

Veritas Volume Manager: Volume doesn't create "rdsk" entry

Add'l info:  I noticed some error messages on the console:

vxvm: vxconfigd: WARNING: Cannot create device /dev/vx/dsk/dskgrp2/my-vol:
value too large for defined type

The only reference to this type of "Cannot create device" type message is in
the VM System Admin Guide, Appendix A, "VM Error Messages".  It states that
this should only happen if the root file system has run out of inodes.  This
definitely is not the case, as this is a new system and `df` reports over
56k free files.

Any idea what value is "too large" that the error message is referring to?

Just a guess, what is the current value of MAXMINOR (& MAXMAJOR).

# /etc/conf/bin/idtune -g MAXMINOR
0x3ffff 0x3ffff 0xff    0x3ffff
