I recently upgrade to Fedora 19 from 17. Fedup did not work correctly, so I did a clean install on the system disk. However, I have a data disk that is raid-1 and has a volume group and logical volumes that were create under Fedora 17 and was not giving any errors. Now with Fedora 19 on mounting the logical volume, the following errors are reported: [ 130.432660] Buffer I/O error on device dm-1, logical block 119570432 [ 130.432664] lost page write due to I/O error on dm-1 [ 130.432674] JBD2: Error -5 detected when updating journal superblock for dm-1-8. [ 130.432701] Aborting journal on device dm-1-8. [ 130.432705] Buffer I/O error on device dm-1, logical block 119570432 [ 130.432706] lost page write due to I/O error on dm-1 [ 130.432708] JBD2: Error -5 detected when updating journal superblock for dm-1-8. [ 218.261625] EXT4-fs (dm-1): previous I/O error to superblock detected [ 218.261640] Buffer I/O error on device dm-1, logical block 0 [ 218.261642] lost page write due to I/O error on dm-1 [ 218.261644] EXT4-fs error (device dm-1): __ext4_journal_start_sb:60: Detected aborted journal [ 218.261647] EXT4-fs (dm-1): Remounting filesystem read-only [ 218.261649] EXT4-fs (dm-1): previous I/O error to superblock detected [ 218.261653] Buffer I/O error on device dm-1, logical block 0 [ 218.261654] lost page write due to I/O error on dm-1 I don't think that this is a hardware problem as everything was working fine before the upgrade to Fedora 19 Any suggestions are welcome.
