Here is how to clear question marks in ls -l following a disk crash
- To free pagecache
echo 1 > /proc/sys/vm/drop_caches
- To free dentries and inodes
echo 2 > /proc/sys/vm/drop_caches
- To free pagecache, dentries and inodes
echo 3 > /proc/sys/vm/drop_caches
$ sudo -i # echo 1 > /proc/sys/vm/drop_caches
... wait ... try
ls /nfs/scratch/A/xyz/protomer/I.. still didn't work
..wait ... try
ls /nfs/scratch/A/xyz/protomer/I
again, worked
and this
lvscan pvscan vgchange -a y mount -t ext4 /dev/vg_system/lv_root /mnt/resh5
finally, reboot gimel if nothing else works.
