[lustre-discuss] Error destroying object

Thu May 3 03:34:17 PDT 2018

Hello Andreas,

Thanks for you answer.

[root at storage06 ~]# debugfs -c -R "stat O/0/d$((0x1bfc24c %
32))/$((0x1bfc24c))" /dev/mapper/ost001c | grep -i fid
debugfs 1.42.13.wc6 (05-Feb-2017)
/dev/mapper/ost001c: catastrophic mode - not reading inode or group bitmaps
  lma: fid=[0x100000000:0x1bfc2c7:0x0] compat=8 incompat=0
  fid = "18 93 02 00 0b 00 00 00 3c c2 01 00 00 00 00 00 " (16)
  fid: parent=[0xb00029318:0x1c23c:0x0] stripe=0

[root at node024 ~]# lfs fid2path /lustre/ 0x100000000:0x1bfc2c7:0x0
ioctl err -22: Invalid argument (22)
fid2path: error on FID 0x100000000:0x1bfc2c7:0x0: Invalid argument

[root at node024 ~]# lfs fid2path /lustre/ 0xb00029318:0x1c23c:0x0
fid2path: error on FID 0xb00029318:0x1c23c:0x0: No such file or directory

Am I doing right? I think so, actually looks like the file is already gone
as I tought in the first moment..

About the hang thread , I've filtered like this and couldn't find nothing
that might indicate the issue, what else we can check for solve this error?
