Here is it: [2011-07-09 02:39:14.798565] I [afr-common.c:902:afr_fresh_lookup_cbk] 0-gfs-replicate-1: added root inode [2011-07-09 02:39:14.798862] I [afr-common.c:801:afr_lookup_done] 0-gfs-replicate-1: background meta-data entry self-heal triggered. path: / [2011-07-09 02:39:14.800398] I [afr-self-heal-common.c:537:afr_sh_mark_sources] 0-gfs-replicate-1: split-brain possible, no source detected [2011-07-09 02:39:14.800552] E [afr-self-heal-metadata.c:518:afr_sh_metadata_fix] 0-gfs-replicate-1: Unable to self-heal permissions/ownership of '/' (possible split-brain).

According to the sources, these are used to detect split brain: silo# getextattr -x system trusted.afr.gfs-client-3 /export/wd3a/ /export/wd3a/ 00 00 00 00 00 00 00 02 00 00 00 00 silo# getextattr -x system trusted.afr.gfs-client-2 /export/wd3a/ /export/wd3a/ 00 00 00 00 00 00 00 00 00 00 00 00 hangar# getextattr -x system trusted.afr.gfs-client-3 /export/wd3a/ /export/wd3a/ 00 00 00 00 00 00 00 00 00 00 00 00 hangar# getextattr -x system trusted.afr.gfs-client-2 /export/wd3a/ /export/wd3a/ 00 00 00 00 00 00 00 02 00 00 00 01 I tried removing these attributes and the errors are gone, but the problem remain: none of the file from these two bricks are seen by readdir. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz manu@xxxxxxxxxx
