This is very slow. But, is it possible that your tar command is too clever? On a 85GiB volume with 370000 files I see the following: # date; tar -c -f - . | cat >/dev/null; date Wed May 13 13:44:29 CEST 2015 Wed May 13 13:59:48 CEST 2015 # date; tar -c -f /dev/null . ; date Wed May 13 14:00:16 CEST 2015 Wed May 13 14:00:20 CEST 2015 # date; vos dump -id 536978585 -time 0 -localauth >/dev/null; date Wed May 13 14:02:23 CEST 2015 Dumped volume 536978585 in stdout Wed May 13 14:27:31 CEST 2015

Probably it has to do with that the volume has many files (in relative few directories). $ vos exa 537086828 -c pdc.kth.se -ext common.var.easy.a-pop.backup 537086828 BK 5084378 K used 2367409 files On-line Harald. _______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
