ext3 to ext4 problem

gabrielsousa · 07-04-2015, 07:26 AM

my tools on centos 5.11

1- kernel - 3.2.69
2- util-linux-ng-2.17 ( mount 2.17 )
3- e2fsprogs-1.41.14
4- grub-1.97
this tool and kernel are all working

-my steps

Code:

-boot on recovery
-change the fstab (/dev/VolGroup00/LogVol00 / ext4 defaults 1 1)
-mount -o remount,ro /
-e2fsck -pf /dev/VolGroup00/LogVol00
-tune2fs -O extents,uninit_bg,dir_index /dev/VolGroup00/LogVol00
-e4fsck -yfD /dev/VolGroup00/LogVol00

and dont work, kernel panic dont mount my LogVol00

what i'm doing wrong ? or what i'm missing ?

the error is

Code:

EXT3-fs (dm-0): error: couldn't mount because of unsupported optional features (40)
mount: error mounting /dev/root on /sysroot as ext3: Invalid argument

shouldnt be EXT4-fs ????

i change the fstab

Code:

/dev/VolGroup00/LogVol00 /                       ext4    defaults        1 1
LABEL=/boot              /boot                   ext4    defaults        1 2
tmpfs                    /dev/shm                tmpfs   defaults        0 0
devpts                   /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                    /sys                    sysfs   defaults        0 0
proc                     /proc                   proc    defaults        0 0
/dev/VolGroup00/LogVol01 swap                    swap    defaults        0 0

boot the OS

Code:

/dev/mapper/VolGroup00-LogVol00
                               ext4    14283576   6394836   7151460  48 /
/dev/sda1                      ext4      101086     40743     55124  43 /boot
tmpfs                         tmpfs     2022980         0   2022980   0 /dev/shm

i can assume that kernel and mount are in the right version to work ext4

is the

Code:

tune2fs -O extents,uninit_bg,dir_index /dev/VolGroup00/LogVol00

thats is killing my FS ?

fix my problem

recompile the kernel without EXT3 fs
and now kernel calls the EXT4-fs

but why with EXT3 and EXT4 the kernel calls EXT3-fs ???
