Basically this is a harmless message which I inserted to know how many pseudo-links will be used. When the number is larger than AUFS_PLINK_WARN which is defined in include/linux/aufs_type.h, this warning is produced. Since this large number can be a memory pressure. So I'd recommend you to flush the aufs pseudo-links by remount or auplink script. The easiest way is, - install all aufs scripts to /sbin (as described in README) - sudo mount -o remount,noplink,plink /your/aufs If you don't want to see this message, try changing AUFS_PLINK_WARN or hiding kern.warn syslog. > aufs au_copy_file:226:dpkg[10011]: copying a large file 6801323 This is an informational message too. When the copying-up file is larger than 4GB and CONFIG_AUFS_DEBUG is enabled, aufs produces this message with kern.warn. > aufs may_rename_srcdir:409:thunar[14455]: renaming dir who has child(ren) on > multiple branches, is not supported This is a feature of aufs. See below in detail. The message is produced once in 256 times when aufs detects such case. (from the aufs manual) ---------------------------------------------------------------------- To rename(2) directory may return EXDEV even if both of src and tgt are on the same aufs. When the rename-src dir exists on multiple branches and the lower dir has child(ren), aufs has to copyup all his children. It can be recursive copyup. Current aufs does not support such huge copyup operation at one time in kernel space, instead produces a warning and returns EXDEV. Generally, mv(1) detects this error and tries mkdir(2) and rename(2) repeatedly. So the result is harmless. If your application which issues rename(2) for a directory does not support EXDEV, it will not work on aufs. ---------------------------------------------------------------------- Junjiro Okajima ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Register now and save $200.
