Hi , Could some one please help me with the below issue. I have booted a mips based hardware with linux (4.4.36 kernel )image(over tftp) and rootfs over nfs by passing nfsroot command line option to the kernel. rootfs is mounted under / in my hardware environment. 192.168.113.254:/rootfs / type nfs (rw,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.113.254,mountvers=3,mountproto=tcp,local_lock=all,addr=192.168.113.254) I have a hard disk and i am mounting it on /mnt , this /mnt directory is part of nfsroot. e2fsck -f -y /dev/sda1 -> disk is clean with no errors. mount -t ext2 /dev/sda1 /mnt (mount was successful ,mounting ext2 using ext4) touch /mnt/test.log -> this command is failing. umount /mnt reboot when i was executing the above commands in a loop i see that /dev/sda1 file system is getting corrupted. touch command is failing with "ext4_find_dest_de:1809: inode #2: block 771: comm touch: bad entry in directory: rec_len %4 !=0 -offset =0(0), inode=4278190080,rec_len=54507,name_len=229 touch : cannot touch /mnt/test.log structure needs clearing" error. I am able to reproduce this issue always when i boot rootfs over nfs , if i boot from hard disk , i am not noticing the issue . Could someone please help me on this , what could cause the ext4 file system corruption. Thanks, Rajesh Dasari.
