Hi Linux gurrus hope you all will be doing well. Well I am facing a problem first time in my sys admin experience. I am using RHEL-4, I am unable to access /boot partition. when i try to access this partion or want to show its contents, It seems /boot is corrupted. see the following outputs #ls /boot/ 9?^?????tdÜ°??????4?çj? #df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/VolGroup00-LogVol00 145G 98G 40G 72% / /dev/sda1 1.4T 1.4T 0 100% /boot none 501M 0 501M 0% /dev/shm Note: its showing the wrong entries /dev/sda1 (1.4T) and its 100% full. #fdisk -l Disk /dev/sda: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 9726 78019672+ 8e Linux LVM Disk /dev/sdb: 80.0 GB, 80000000000 bytes 255 heads, 63 sectors/track, 9726 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sdb1 * 1 9726 78124063+ 8e Linux LVM Can any body help me whats wrong with /boot? Number of applications are being run (24x7) on this server. I cant reboot it and cant interrupt the running applications. Can any body tell me what should i do now? Server's info: #cat /etc/redhat-release Red Hat Enterprise Linux ES release 4 (Nahant Update 5) # uname -r 2.6.9-11.ELsmp waiting for an early response. Thanks Sohail
Normally I'd say "boot from a rescue CD or rescue system and try to delete some unneeded files in /boot", but this doesn't work if you can reboot the system... Does this work? Code: cd /boot ls -l
i have the same problem. root@montreal [/boot]# cat /etc/redhat-release CentOS release 5.4 (Final) root@montreal [/boot]# uname -r 2.6.18-164.el5 root@montreal [/boot]# df -h Filesystem Size Used

guped, you issue is not the same. all you need to do is uninstall the old kernels that you are not using.
