mirroring: "ksh: cannot create" errors after primary drive failure
Desc: The customer has mirrored, using two disks, a non-rootvg volume
group. He has turned off quorum checking with "chvg -Q n VGname"
and varied off and back on the volume group for this to take
effect. He then tests this by failing the primary drive.
Now, when he tries to create files, he gets errors. Specifically,
on the following commands he gets the following results:
\# date > fn
ksh: cannot create
However, ls -l shows that the file is created, with length 0.
On the successive iteration of the SAME command, the output is
successfully written to the file with no error.
However, on successive iterations of the two commands in order
reproduces the same output.
Action: On both a 3.2 and 4.1 system, I reproduced the same errors
when I DID NOT mirror the log device for the volume group
(the log device sits on the primary device).
The log device for the customer's volume group is loglv00.
Mirrored it with "mklvcopy -k loglv00 2 hdisk2" and this
corrected the problem.
