no jestli nemuzes data zalohovat, tak stejne muzes zkusit dir_index, jak uz tu radili, myslim musis nabootovat nejakou live distribuci, na namountovanym to nepujde:
tune2fs -O dir_index /dev/md0
e2fsck -D /dev/md0
a pak muzes zkusit na namountovanym e4defrag
a tyto mount parametry v /etc/fstab mas? noatime,stripe=x, vono by to bylo lepsi preformatovat jeste se stride, ale jestli nemuzes, tak alespon dej spravny stripe...
stripe=n Number of filesystem blocks that mballoc will try
to use for allocation size and alignment. For RAID5/6
systems this should be the number of data
disks * RAID chunk size in file system blocks.
a nemel jsi puvodne ext3 a potom nekonvertoval na ext4?
