bdf: /mountpount: I/O error

[Thalima León]

I have any problem with this mount point. This point is actived when I need take a backup and this point is mount in another server. The backup was made with Business Copy, when the resyc was made the structure was mount in another server. Now the operating system disallow me to have vgchange -a n /dev/vgbc send me: vgchange: Couldn't deactivate volume group "/dev/vgbc":
Device busy
I need inactive it, I have different posible form, I can't inactive the server now.

There is obviously an open process on the filesystem.

fuser -cu /filesystem_name

fuser -cuk /filesystem_name

kills all open processes.

Then you should be able to umount the filesystem.

Otherwise the only other way to go is to restart the system and try after boot.

lsof utility can be useful sometimes in identifying what process is giving you trouble.
