BMT pageCnt is decreasing on AdvFS usr_domain & var_domain domains

Problem :"BMT pageCnt is decreasing on AdvFS usr_domain & var_domain domains . "

OS: 4.0f

The suggestions someone gave is that using vdump to backup the /var&/usr , vrestore them after remkfdmn the /var&/usr domain .

since no new disk to apply in this case, is any other way to solve this problem ?

If I use OS CD to boot up from CD-ROM, what should I do after booting up?

Thanks

Hi,

you have another option, if you have the advfs-utilities and more space. You can use addvol for more space.
How full is the domain now and do you frequently defragment it?

Hi,

you can do a manual defragment by
defragment -v usr_domain
Please also look with
crontab -l | grep defrag
whether the defragment is active or
commented out.
For more info see man defragment.

Re: BMT pageCnt is decreasing on AdvFS usr_domain & var_domain domains

the following methods are possible:

1. Migration.

o add a volume (same size or bigger) to this domain and then removed the current volume. this should compact the metadata file and give you more free extents. then, defragment your news domain.
o Refer to the manpage on migrate, addvol, and rmvol.
o addvol {add a new volume}
o showfile -k domain {note new volume index number}
o to migrate files from existing volume-index to new vol-index, can rmvol (part of rmvol is migrate existing files).

o once the volume is removed, repeat, using the removed volume as the new volume.

2. vdump/vrestore

o dump the entire fileset, rebuild the volume, vrestore.
o sucess depends on the dump/restore and the time required to do this.

o the hard way is to dump the domain, recreate the domain. before restoring the newsfileset to the new domain you can create a few thousand empty files and delete them.
