Problem in recovery of superblock of RHEL5.
Respective sir,
I am new user of RHEL5 since last two weeks I face problems in my RHEL5.I describe these problem asfollow. 1)When I start my machine that time I got message on black screen that (Hardware monitor found error. please go in power setup menu.)and (last time your system hung for improper cpu speed please adjust it) 2)To solve this problem I have change hardware monitor option in bios and also I have increase my cpu speed manually.above problem get solved but after that when I restart my machine. I have got same problem . 3)above two problems are related with hardware but when I solve above problem and after that when I start RHEL5 in single mode and I had type fsck on command prompt. I dont know what happened after that. But I got error of kernel panic. this error was resolved automically after that day my system was not get start in single mode as well as in graphical mode. 4) to solve my RHEL5 problem I try by rescue mode. but when I enter in setup i got message that their is no RHEL5 on this drive.when I try fresh installation all partitions are shown.but at this stage I have not install fresh RHEL5. 5) To solve this problem no:4, I install RHEL5 in another Hard disk and I type fdisk -l command on terminal of new RHEL5. I got description of both of my disks.I have two VFAT(fat) partitions, one boot,one root, one swap and one extended partition on my old hard disk. so I use mount command to mount old RHEL5 containts but only two VFAT and boot partitions get mounted . when I try to mount my root and other partitions I got message that (Unknown fs or bad superblock,try dmesg,so|tail) 6) to solve problem of superblock I use (fsck -b /dev/hdc2) this command but I got message that cant recover super block. no ext3 is on this drive. 7) please help me to get out of this problem because I have very Important data on my root directory. 8) I dont want to format this RHEL5 I want to solve this problem without formating RHEL5. Respective sir please send me answers of this questions in details. i.e why this problem come and what to do to solve it. |

And don't post follow-ups after five minutes. We volunteer our time here. You need to boot off of a CD/DVD..you SHOULD NOT fsck a hard drive when it's mounted, and you can't unmount the / partition when you're booted. |
yeah TB0ne is very right ...
u should provide some more details regarding your problem.. all of one remounting your filesystem should solve this ..if it doesnt..there should be more details needed...to get into the root of the issue... try Quote:
fsck doesnt work when your drives are mounted.. |
