Dear All, My servers running on CentOS 5.5 x86_64 with kernel 2.6.18.194.17.4.el gigabyte motherboard and 2 harddisks (seagate 500GB). My CentOS box configured RAID 1, yesterday and today I had the same problem on 2 servers with same configuration. See the following error messages for details: EXT3-fs: INFO: recovery required on readonly filesystem. EXT3-fs: write access will be enabled during recovery. kjournald starting.
