i am using redhat 5.4 and my root size shows 98 %, how can i increase root size
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 77G 16G 75G 98% /
/dev/sda1 2.4G 82M 2.2G 4% /boot
tmpfs 3.8G 0 3.8G 0% /dev/shm
none 3.8G 104K 3.8G 1% /var/lib/xenstored
pls suggest
Maybe any live CD/USB with gparted can help? If you do not have any space on sda1 I think you should either remove something or buy another disk...
Sorry if this is a fool suggestion.
no i have space. i have created 10 Gb lvm, now i want to increase root size...
/dev/sda2 77G 16G 75G 98% /
here 16 GB is used then how come 98% filled check the system.....
Ravi,
As with other logical volumes you cannot the extend / volume easily.
df output shows only 16 GB is used, check the list of all the open files via lsof command so that you can get an idea which is causing high disk space consumption by looking at the output.
Something does not make any sense here.
First of all the OP states that he is using LVM but that is not what df output shows.
Second, the df output for / is suspicious.
In case you created a new 10 GB logical volume (besides your non-LVM root disk), you cannot attach a logical volume to a disk that is not managed by LVM.
Please post the output of:

Your root partition is not part of an LVM so you can't directly attach your volume named "lvm".
It's possible to migrate your information from a standard root partition to a logical volume. You'll just need a large enough logical volume (77 GBs >)
Keep in mind that downtime is required as you cannot perform it while / is mounted.
