[Lustre-discuss] Problems with lfs find

I have an odd problem. I am trying to empty all files from a set of OST
as indicated below, by making a list via lfs find and then sending that
list to lfs_migrate. However, I have just gotten this message back from
the lfs find:
llapi_semantic_traverse: Failed to open
'/lustre/umt3/data13/daits/p15.6.3.10/prod/W1J_munu216465_simul': No
such file or directory (2)
error: find failed for umt3-OST0021.
The running script contains the following, active code lines:
umdist03OBD="-obd umt3-OST001c \
-obd umt3-OST001d -obd umt3-OST001e \
-obd umt3-OST001f -obd umt3-OST0020 -obd umt3-OST0021 "
#
lfs find /lustre/umt3 ${umdist03OBD} > ./check_umdist03.txt
dmesg on the machine where this ran shows nothing.
There are still some 60GB of files on this target server, spread more or
less evenly over the 6 OST. dmesg on the MGS shows no errors at this
point. On the OSS, I see this but not much else:
LustreError: 5226:0:(ldlm_resource.c:861:ldlm_resource_add()) lvbo_init
failed for resource 9101: rc -2
Can someone give me an idea of what is wrong here? And what can be
done about it, if anything?
Thanks,
bob
