[MooseFS-Users] Is it safe to rename mountpoints in mfshdd.cfg?

[Michael T. <mic...@ho...>]

It's me again with a different question.


Through the years one of my chunkservers have gone through several disk replacements, upgrades, and additions. Disks are mounted in /mnt and named mfshdd<seq> with <seq> being a through z, ie. mfshdda, mfshddb, and so on.  It started out with 3 disks, mfshdd[a-c], and now it is up to the letter i.  mfshdd.cfg now looks like:


/mnt/mfshdda

#/mnt/mfshddb

/mnt/mfshddc

/mnt/mfshddd

#/mnt/mfshdde

/mnt/mfshddf

#mnt/mfshddg

#mnt/mfshddh

/mnt/mfshddi


I'm toying with the idea of changing a couple of the mountpoints so that I have no holes in the sequence.  The steps I'm thinking of is:


(a) stop moosefs-chunkserver

(b) remount mfshddi as mfshddb, and mfshddf as mfshdde.

(c) edit mfshdd.cfg to reflect this change

(e) start moosefs-chunkserver


Is this doable without losing out the chunks that are expected to be in mfshddf and mfshddi?  They're still there anyway, just in a different mountpoint.  Will they be recognized as valid chunks when the chunkserver is started back up and it scans the folders?
