Remounting filesystem with read/write attributes

Here are few ways of remounting a file system with read/write attributes after being mounted as read only:

[root@server1 ~] # mount -o remount,rw /dev/mapper/VolGroup00-LogVol00
[root@server1 ~] # hdparm -r 0 /dev/mapper/VolGroup00-LogVol00
[root@server1 ~] # blockdev --setrw /dev/mapper/VolGroup00-LogVol00
