[SOLVED] faster way to recursively change ownership of large filesystem

pople · 09-16-2014, 07:34 PM

Looking around I have not seen this addressed for large file systems. I have a 1Tb drive that I mount using the following script:

Code:

#!/bin/bash

md1=$(blkid -U d81fc8e7-7081-4872-9667-8fd5da730df2)

cryptsetup luksOpen $md1 d1 && echo "d1 Unlocked"

mount /dev/mapper/d1 /home/bob/d1/

chown bob:bob /home/bob/d1/ -R && echo "Done Mounting d1"

My question is can the process be sped up by using a command other than chown to recursively change ownership of the mount point? I don't think I can make an addition to my fstab because the /dev/sd* varies between boots. Hence the blkid command. Anyone have any thoughts on this? I have skimmed through the mount man pages but have not found anything that works yet. I have also tried the uid option.

Well I had a face palm moment when I realized that /dev/mapper/d1 was what I was actually mounting. I have amendend the script and made a corresponding fstab entry.

Code:

#!/bin/bash

md1=$(blkid -U d81fc8e7-7081-4872-9667-8fd5da730df2)

cryptsetup luksOpen $md1 d1 && echo "d1 Unlocked"

su bob -c "mount /dev/mapper/d1"

/etc/fstab looks like:

Code:

/dev/mapper/d1         /home/bob/d1 auto                user            0 0

now it is FAST!!!!
