Operating Systems Linux Red Hat How to resize filesystem by resizing the LUN without impact to applications.? Post 302830011 by Just Ice on Sunday 7th of July 2013 09:33:34 PM

you can change the filesystem while it is running but you are asking for a disaster to happen ... essentially, you will be creating files and then messing up the filesystem underneath it ... it would be similar to jumping into a sand pit expecting a fairly solid spot but getting quick sand instead ...

i strongly advise against resizing filesystems while they are running or in use but if you really want to try it -- try testing the process you envision on a "disposable" server with LVM enabled and confirm if the risks involved are acceptable ...

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

NAME
local-filesystems - event signalling that local filesystems have been mounted SYNOPSIS
local-filesystems [ENV]... DESCRIPTION
The local-filesystems event is generated by the mountall(8) daemon after it has mounted all local 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 in order for remote filesystems, if any, to be activated. Remember that some users may not consider it wrong to place /usr on a remote filesystem. 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 local filesystems are mounted might use: start on local-filesystems SEE ALSO
mounting(7) mounted(7) virtual-filesystems(7) remote-filesystems(7) all-swaps(7) filesystem(7) mountall 2009-12-21 local-filesystems(7)
