MySQL ufsdump...
hi.

it`s no problem to make an ufs-dump to a mounted filesystem, but the meaning is this: if you want a "consistent" state of datas, no process have to write to a file you wanna back up; so when you are really shure NO process is writing to the datas you want to back up, you can run "ufs-dump" unmounted. (check if there are processes with "fuser <dir>" or freeware "lsof").

when you are not shure, go to single-user mode to "kick" all user-processes from the system. but when you wanna be really shure, umount the filesystems to backup, cause there are always systemprocesses writing to filesystems like /var.

best regards,
alex...

remote-filesystems(7)					 Miscellaneous Information Manual				     remote-filesystems(7)

NAME

       remote-filesystems - event signalling that remote filesystems have been mounted

SYNOPSIS

       local-filesystems [ENV]...

DESCRIPTION

       The  remote-filesystems event is generated by the mountall(8) daemon after it has mounted all remote filesystems listed in fstab(5).  moun-
       tall(8) emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with  other
       activity.

       This event is typically used by services that must be started to manage remote filesystems.  When it occurs, local filesystems such as /usr
       may not be mounted.  For most normal services the filesystem(7) event is sufficient.

       This event will never occur before the virtual-filesystems(7) event.

EXAMPLE

       A service that wishes to be running once remote filesystems are mounted might use:

	      start on remote-filesystems

SEE ALSO

       mounting(7) mounted(7) virtual-filesystems(7) local-filesystems(7) all-swaps(7) filesystem(7)
