We have a virtual Linux server (Fedora Core 18.104.22.168-45.fc14.x86_64) running on VMWare vSphere. Initially it had 3 SCSCI drives 32Gb each. Now we have extended a disk that was mounted under "/home" to 256GB. But Linux server, obviously, does not see that change after restart. Is there a safe way to extend that ext4 partition from 32GB to 256GB withou losing any data?
I've made a search on Google before asking this question and many advice to use GParted. But it seems not the option for me now as I only have shell access to that server at the moment.
EDIT: This is an output from df:
[root@d0001-prf01 dmr]# df -T Filesystem Type 1K-blocks Used Available Use% Mounted on /dev/mapper/vg_d0011prf01-lv_root ext4 31705024 3385376 27997620 11% / tmpfs tmpfs 4098300 88 4098212 1% /dev/shm /dev/sda1 ext4 495844 31317 438927 7% /boot /dev/mapper/vg_d0011prf01-lv_home ext4 23674012 11840672 10630756 53% /home
I can provide more partition information if needed.
EDIT: I can see that LVM is set up on that Linux server:
lvm> lvs LV VG Attr LSize Origin Snap% Move Log Copy% Convert lv_home vg_d0011prf01 -wi-ao 22.94g lv_root vg_d0011prf01 -wi-ao 30.72g lv_swap vg_d0011prf01 -wi-ao 9.81g
Does it mean I can use lvresize command?
