getting data back from a partition after installing new RHEL 5.5.

[bilal_jan]

Hello everyone output of fdisk -l on my Redhat 5.5 is as follows

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1        2490    20000893+  83  Linux
/dev/sda2            2491        9729    58147267+   5  Extended
/dev/sda5            2491        2614      995998+  82  Linux swap / Solaris
/dev/sda6            2615        7594    40001818+  83  Linux
/dev/sda7            7595        9729    17149356   83  Linux

While mount commad output is as follows

/dev/sda1 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
none on /var/lib/xenstored type tmpfs (rw)

before installing Redhat i was using Ubuntu on my system and i have some very precious data stored on sd6 and sd7.
what should i do to mount sd6 and sd7 into my Redhat distro to get my data on sd6 and sd7 read by rhel 5.5
thanks

It looks like data is intact in sda6 and sda7 because RH is using only sda1 partition.
In which filesystem sda6 and sda7 have been formatted?
Have you tried to mount sda6 partition manually?

su -
cd /media
mkdir sda6 sda7
mount -t  filesystem  /dev/sda6  /media/sda6
mount  -t  filesystem /dev/sda7  /media/sda7

Check /media/sda6 and sda7 folders.

In case it doesn't work, you have to boot up from Ubuntu LiveCD and mount both partitions.

u got it so right

thanks man

i tried ext2,ext3 both of them didnt worked so i treid ext4 it worked.
is there any way to check wt filesystem these partitions are using?

Usually if you omit the type information when mounting a partition, mount will figure it out for you. However, sometimes it can't and you will have to supply the type to it. At least you were able to get the ext4 drivers with your RHEL system. I think it has been included in the latest kernel updates. I know it is now on my CentOS 5.5 system (running latest kernel) and the dates on the ext4 tools (fsck, mkfs) are March 31, 2010. Of course that may correspond with the last time I configured and built a custom kernel as well...

Execute blkid command with root privileges to check filesystem of partitions.
In Ubuntu, execute this

sudo blkid

Re. blkid - thanks DC. I forgot about that. Must be one of those senior Fritz (as in Alzheimer) moments!
