So this didn't help, today I got:

  whimsy.med.utah.edu    /sstore/gen6   lev 2  FAILED [dumper returned FAILED]
  clarity.med.utah.edu   /sstore/gen10  lev 0  FAILED [data timeout]
  clarity.med.utah.edu   /sstore/gen10  lev 0  FAILED [dumper returned FAILED]
  whimsy.med.utah.edu    /sstore/gen6   lev 2  FAILED [too many dumper retry: 
"[request failed: timeout waiting for REP]"]
  whimsy.med.utah.edu    /sstore/gen6   lev 2  FAILED [cannot read header: got 
0 instead of 32768]
  clarity.med.utah.edu   /sstore/gen10  lev 0  FAILED [cannot read header: got 
0 instead of 32768]
  clarity.med.utah.edu   /sstore/gen10  lev 0  FAILED [too many dumper retry: 
"[request failed: timeout waiting for REP]"]
  serenity.med.utah.edu  /sstore/9gb    lev 1  FAILED [data timeout]
  serenity.med.utah.edu  /sstore/9gb    lev 1  FAILED [dumper returned FAILED]
  serenity.med.utah.edu  /sstore/9gb    lev 1  FAILED [cannot read header: got 
0 instead of 32768]
  serenity.med.utah.edu  /sstore/9gb    lev 1  FAILED [too many dumper retry: 
"[request failed: timeout waiting for REP]"]

i.e., problems with all the file systems on this drive.  I have my
timeouts set to:

etimeout                100000
dtimeout                3600
ctimeout                60

Should I increase them?  Which one?  Any other ideas?

Thanks,
  Steve
