Dear Team ,
my server is Hp server . Whihc I install the ERP App & DB on it .
The Operating system is Linux 2.6.18-194.el5 x86_64
/dev/cciss/c0d0p5 111G 43G 63G 41% /u03
/dev/cciss/c0d0p3 119G 109G 3.9G 97% /u01
/dev/cciss/c0d0p2 119G 104G 8.7G 93% /u02
As you See Up there no size in /U01 & /U02 Now I want Add 2 Internal Hard disk on the Slot 60 G + 60 G = 120 G
And want to mount this 60G to /u01 & 60G to /u02
so U01 it become 179 g and U02 it become 179 g withuot dirstub the current configration of DB & Application
its my test server . kindly advise how i can do this . as I am not a ware with Linux OS
You don't say what kind of filesystem /u01 & /u02 are, but if they are EXT file systems, then get their UUUID:
# blkid /dev/cciss/c0d0p3
And then mount the file system based on the UUID with an /etc/fstab entry like:
UUID="abcdef" /u01 ext3 defaults 0 1
This way, it won't matter that the device names will change as LUNs are added or removed. The UUID is an attribute of the filesystem on the LUN, so a different LUN name won't matter in the least.
You cannot simply add disks to increase the storage space of any particular partition unless the device is under LVM control. Instead of LVM however, Oracle recommends to use ASM, which allows you to re-size existing disk groups online by adding new storage devices. Anyway, I'm afraid you are asking for procedures that are too complex to explain here.
