Is there a way to perform a safe reduce in rootlv at rescue mode? Most of the internet's explanations tells, basically, that it can be done using the following steps sequence:
vgchange; fsck; resize2fs; lvreduce; reboot
I tried it a several times; but all I get when system pass through POST is the same error:
FATAL: INT18: BOOT FAILURE
Is that a way to do that safely?
