[Lustre-discuss] Problems with lfs find

[Bob Ball]

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
