I have about six domains on my system that give the following
warning when sys_check runs. At first I examined them all
and they were heavily fragmented, but now I have defragmented
them all and the warning message persists. Is there anything
that can be done to get rid of the warning short of totally
remaking the volume on a different disk and vdump/vrestore?
If I have read the sys_check script correctly, it triggers this error
message when it sees a low PageCnt in the second column, third line
or better, such as the 10 that appears in the 2nd column 3rd line below.
All the domains in question have something like this going on.
Thanks for any help you can provide.

Output of showfile -x M-6 for ksera41cdmn domain:
Note: BMT pageCnt is decreasing on AdvFS ksera41cdmn domain.
Check the domain immediately.
This may indicate that a BMT extension could not (temporarily) get enough
disk space. It can
also be due to the domain being full or fragmented. Use the AdvFS
Utilities command addvol to
correct the problem and then invoke the rmvol command on the volume(s).
