Re: [BackupPC-users] Only v0 showing in backup history
OK, another update which may help people. I submitted an issue with bindfs (http://code.google.com/p/bindfs/issues/detail?id=20). Turns out there are some options to use with bindfs relating to inodes (actually they are FUSE options 'use_ino' and 'readdir_ino' but see issue above). These options are on by default in more recent versions of bindfs than I'm currently running.

By way of background, our backup setup is as follows: - Linux BackupPC server on ESX - Backup media on cheap SAN mounted via NFS - BackupPC directory remounted using bindfs (http://code.google.com/p/bindfs/) to get the user/group as backuppc The problem (only v0 showing) is occurring as a result of readdirent (from IO::Dirent) returning the value 4294967295 for all inodes - DirHistory detects v0, v1, etc buy looking for updated inodes on the backed up files. The problem only seems to occur for me only on the bindfs filesystem. I have attached a test program which I've used to confirm the problem. It produces output like this: root@XXX:/home/XXX# ./test.pl Test program /bindfs/backuppc/: F: . 4294967295 F: .. 4294967295 F: cpool 4294967295 ... /nfs/backup/backuppc/: F: . 3604481 F: .. 3424257 F: cpool 3604482 ... My proposed fix is attached as a patch file. I have extended the section in dirRead() titled Make sure the IO::Dirent really works to include a check for inodes with the value 4294967295 (-1 in 32-bits) and flag the use of stat() in place of readdirent(). Comments welcome. For your consideration Craig. I will also submit an issue with bindfs to query them on this issue.
