Thread: EXT4 problem: switch to read-only mode when folder lost+found is accessed
hi,
have weird problem here 9.04 server. have raid 5 disk formatted in ext4 remounted automatically when accessed lost+found folder in root of disk.
error in syslog is:
i ran e2fsck no results.code:jan 19 11:14:45 ipf-srv001 kernel: [ 5478.859996] ext4-fs error (device sdb1): ext4_iget: bad extended attribute block 50599009714176 in inode #25338 jan 19 11:14:45 ipf-srv001 kernel: [ 5478.860003] aborting journal on device sdb1:8. jan 19 11:14:45 ipf-srv001 kernel: [ 5478.860051] remounting filesystem read-only
tried delete can't. it's bit annoying because have prevent users , backups access folder.
idea how can remove folder?
thanks!

hi,
first off, bit of info lost+found directory. it's directory created everytime filesystem check performed. if file system check (fsck) finds corrupt files, dumps them lost+found folder can file dump , there chance of data recovery.
check link out: http://www.tldp.org/ldp/linux-filesy...lostfound.html
in case, directory have been created every time run e2fsck. since directory owned "root" won't able delete unless become superuser.
there issues ext4 waiting sorted out development team. there possibility problem bug.

meanwhile, can try checking filesystem bad blocks, filesystem hardware errors might cause lot of data corruption might result in frequent disk checks , consequently, large lost+found directories.
let me know if helps.code:man badblocks
