784.0. "LSM and dd fails" by TAV02::ISRAEL () Wed Apr 16 1997 05:41


    Hi All !


    I have seen a problem with dd writing to lsm volume on 4.0b .

    I defined a lsm disk in a sliced way : (disklabel of the disk)

8 partitions:
#        size   offset    fstype   [fsize bsize   cpg]
  a:   131072        0    unused        0     0       	# (Cyl.    0 - 96*)
  b:   262144   131072    unused        0     0       	# (Cyl.   96*- 289*)
  c:  4108970        0    unused        0     0       	# (Cyl.    0 - 3021*)
  d:        0        0    unused        0     0       	# (Cyl.    0 - -1)
  e:        0        0    unused        0     0       	# (Cyl.    0 - -1)
  f:        0        0    unused        0     0       	# (Cyl.    0 - -1)
  g:  4107946        0   LSMpubl                    	# (Cyl.    0 - 3020*)
  h:     1024  4107946   LSMpriv                    	# (Cyl. 3020*- 3021*)


   I also defined 20 lsm volumes on this group. (every volume 50M)

   trying to run a simple dd command to any of the volumes -

   dd if=/genvmunix of=/dev/rvol/diskgroup/vol01 bs=1024

   I got -
   dd : invalid write argument
   7730+1 records in
   7730+0 records out

   And the last record is always incomplete.
   According to my knowledge it happens only on 4.0b .


   Thanks in advance .

	Hi, Don't know the solution, but I have seen the same complaint in the ASE notefile with 4.0B and TRUcluster drd service. Seams that dd has been changed in some way... Manu.
