[CentOS] EXT4 mount issue

Hi All,

When a couple of EXT4 filesystems are mounted in a server I get the message

Oct 1 18:49:42 sraid3 kernel: EXT4-fs (sdb): mounted filesystem without journal Oct 1 18:49:42 sraid3 kernel: EXT4-fs (sdc): mounted filesystem without journal

in the system logs.

My confusion is why are they mounted without a journal? They were both created with

mkfs -t ext4 /dev/sdb mkfs -t ext4 /dev/sdc

and mounted in "/etc/fstab" with

/dev/sdb /sraid3 ext4 defaults 1 2 /dev/sdc /sraid4 ext4 defaults 1 2

both are 11T and so I would prefer as much stability as possible, io performance is not an issue on either device just integrity so I thought the journal would be default and necessary.

Any thoughts would be much appreciated.

Steve
