Files with Question Marks in Directory Listing [dangling d-entries]

Files with Question Marks in Directory Listing [dangling

d-entries]

Issue:

If I go into a particular directory from a segment server I see: [root@ss-3b-uss

IvanMatias]# cd /qtrxfs1/disk3/Music/IvanMatias/TheModSquad [root@ss-3b-uss

TheModSquad]# ls IvanMatiasTheModSquadMessin'Around.mp3 [root@ss-3b-

uss TheModSquad]# [root@ss-3b-uss TheModSquad]# ls -al total 8 drwxr-xr-x 2

root root 4096 Jan 5 2008 . drwxr-xr-x 3 root root 4096 Jan 5 2008 .. ?--------- ? ?

? ? ? IvanMatiasTheModSquadMessin'Around.mp3 [root@ss-3b-uss

TheModSquad]#

Notice the file size above and file info is missing, the file appears to be missing

and has "?" marks, this is not the case for all files, only a few that I

can't seem to pin point to any one thing. Is there a handy way to check or confirm

the file system is all there and working properly?

Solution:

More then likely these are dangling d-entries. Dangling d-entries are files that

have been deleted but were not removed from the directory listing in the parent

directory inode. These entries can be cleaned up with the ibdircheck utility.

Please run the following command on one of the segment servers to perform an

analytic check. /usr/local/ibrix/bin/ibdircheck -s -r -n

/qtrxfs1/disk3/Music/IvanMatias/TheModSquad

Here is the output of the command: [root@ss-2a-uss TheModSquad]#

/usr/local/ibrix/bin/ibdircheck -s -r -n

If all looks good run the following command to fix the dangling d-entries, /usr/local/ibrix/bin/ibdircheck -s -r -y /qtrxfs1/disk3/Music/IvanMatias/TheModSquad IBRIX_S00000036.
