I've forgot the syslog error entry: Jan 24 23:00:02 ay kernel: [371845.888834] EXT4-fs error (device sda2): ext4_iget:3888: inode #127236: comm python-d: bad extra_isize (65663 != 256) Jan 24 23:00:02 ay kernel: [371845.888849] Aborting journal on device sda2-8. Jan 24 23:00:02 ay kernel: [371845.890819] EXT4-fs (sda2): Remounting filesystem read-only Jan 24 23:00:02 ay kernel: [371845.902919] EXT4-fs error (device sda2): ext4_iget:3888: inode #127236: comm python-d: bad extra_isize (65663 != 256) I say "same ext4 file system corruption" because e2fsck reports errors on inodes around 127233 on all file systems. I'm not sure about the syslog errors because i have syslog logs for only the latest faulty partition. ciao Luca
