I don't know pattern of corruption, but according to error message in Dovecot, it seems to expect data to read but reach EOF. All seems fine using fuse_disable_pagecache (no more corruption, and performance increased : no more MDS slow requests on filelock requests). _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
