Brent, the afr's logging in this case are harmless, but we fix the logging priorities soon. I'm not sure about the NFS rexport hanging. I will try to reproduce it at my setup. If the issue with cp -a failing was related to hardlinks, please try patch-371 which has some hardlink related fixes in it. thanks, avati 2007/7/26, Brent A Nelson <brent@xxxxxxxxxxxx>:
I've been testing NFS reexport with cp -pr (from a Sun) of a /usr directory from GlusterFS to GlusterFS. So far, it's been close, but not quite right. The copies never turn out the same, there's always at least some missing files. The cp reports "cannot access" for a lot of items. GlusterFS logs a ton of op_ret=-1 op_errno=61 errors such as the following: 2007-07-25 14:36:43 E [afr.c:1234:afr_selfheal_getxattr_cbk] mirror2: (path=/nfs2/share/zoneinfo/right/Pacific/Johnston child=share2-1) op_ret=-1 op_errno=61 2007-07-25 14:36:43 E [afr.c:1234:afr_selfheal_getxattr_cbk] ns0: (path=/nfs2/share/zoneinfo/right/Pacific/Johnston child=ns0-0) op_ret=-1 op_errno=61 2007-07-25 14:36:43 E [afr.c:1234:afr_selfheal_getxattr_cbk] ns0: (path=/nfs2/share/zoneinfo/right/Pacific/Johnston child=ns0-1) op_ret=-1 op_errno=61 In my tests from today's TLA repository, nfsd is eventually even hanging (this wasn't occurring in earlier patch releases). Following that, I did an ls from the GlusterFS reexport machine of one of the areas that the NFS client recently complained about and got a similar error, but in a different function: 2007-07-25 15:51:10 E [afr.c:563:afr_getxattr_cbk] mirror4: (path=/usr/share/dict child=share4-0) op_ret=-1 op_errno=61 2007-07-25 15:51:10 E [afr.c:563:afr_getxattr_cbk] mirror4: (path=/usr/share child=share4-0) op_ret=-1 op_errno=61 I'm hoping the errors provide some clue to the NFS glitches (and presumably pins the issue down to AFR), but perhaps they're harmless. Any ideas? Thanks, Brent PS An NFS reexport from an extremely simple (no protocol/*, no unify, no AFR; only storage/posix) GlusterFS volume last week seemed fast and trouble-free. If anyone needs NFS reexport and doesn't need AFR, I haven't tested it (yet), but it's definitely worth a shot! _______________________________________________ Gluster-devel mailing list Gluster-devel@xxxxxxxxxx http://lists.nongnu.org/mailman/listinfo/gluster-devel
