Re: [BackupPC-users] missing rdev on device...
Hi Glassfox, since you're ignoring off-list requests to stop posting to this *mailing list* via "Backup Central", let me explain to you on-list, that this is a MAILING LIST (shouting intended), and that you are making an utter fool of yourself by repeatedly generating messages containing Glassfox wrote on 2008-12-22 16:59:41 -0500 [[BackupPC-users] missing rdev on device...]: > > This is an edited version of a previous post You *cannot* edit previous posts. "Backup Central"s official point of view seems to be something like "we only encourage fools to do stupid things, we don't make them do them; if that annoys mailing lists, so what?". They obviously don't grasp the basics of threading and the involved email headers, and, frankly, I couldn't be bothered to explain them to them. It's not that it is *impossible* to follow a mutilated-by-Backup-Central-type thread, it's just that it's a pain, and I, for one, don't voluntarily inflict pain upon myself. I would be happy to continue simply ignoring your posts and the partly incorrect or misleading answers there have been, if not for the fact that all of that lands in the archives and may mislead readers who have done *nothing* to deserve it. So, as for your question, > Any idea what's wrong here? I really couldn't care less.

I must say Glassfox, I have never seen Holger get upset with someone on-list like this. Please change your post methods for our sake.

There is no point in *restoring* a named pipe, because you can't "restore" the process listening "on the other end".

Now THAT'S being unreasonable. I think he posted to say that he would have cared if the person asking would refrain from sending edited posts to the mailinglist via Backup Central. It was not the first time Holger expressed his annoyance with posters coming through Backup Central, so I guess this was just the drop and someone got a reaction that was maybe a bit stronger put than he could have expected. Just my 2 cents, Nils Breunese. -- ___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/

Bugger, I'm in need of restoring my filesystem and I just came across this. It issued a few of these messages, then seems to have paused, with rsync or backuppc not showing any activity according to strace. Dunno whether the incorrect handling of the pipe caused the susequent pause. I'm restoring to blank partitions, so it's not like it's blocking on writing to a pipe on the remote filesystem, since the pipe doesnt exist yet. Note that in my debugging, I have blown away the temporary partition I created, so I can't verify whether it had actually created the pipe yet (one suspects not, if Rsync.pm couldn't handle it). > 1.) /dev/initctl is a named pipe.

You might still want to back up named pipes, for the sake of > having an exact image of your file system for reference or auditing > purposes. Sure you want to restore named pipes (I think you're thinking of sockets). Named pipes are pipes on the filesystem that haev a static name. They can be created temporarily by processes to communicate with another process (but what's the point, that could have just passed over file descriptors to a socket), or they can be pipes that you keep around that are persistent over processes restarting (I first used pipes about 10 years ago to have a music daemon that could block on a pipe until some reader came along. The first pipes backuppc came across when trying to restore my current system was a pipe I created a few months ago in order to work around limitations of a script I was using that wouldnt write to stdout or /dev/stdout, but would write to a named pipe. /dev/initctl for instance always exists in /dev. If you want to restore /dev, then you have to be able to handle named pipes. Also, rsync is able to read and write named pipes. It probably is -D, but in order to restore a filesystem, you need to use -D. > Did all of the error messages refer to named pipes? 2009-01-09 12:47:11 gamow: File::RsyncP::FileList::encode: missing rdev on device file tconnors/.config/gxine/socket 2009-01-09 12:47:11 gamow: File::RsyncP::FileList::encode: missing rdev on device file tconnors/.signature 2009-01-09 12:47:11 gamow: File::RsyncP::FileList::encode: missing rdev on device file tconnors/movies/a2k/handlebar_mounted_SSO_blackburnhill_return/intermediate1.mpg 2009-01-09 12:47:11 gamow: File::RsyncP::FileList::encode: missing rdev on device file tconnors/movies/a2k/handlebar_mounted_SSO_blackburnhill_return/intermediate2.mpg They are named pipes on the system that was backed up and is trying to be restored to. > 2.)

The file exists as an empty file in the full backup. Dunno how to parse the attrib file. in FileList/rsync.h, #define IS_DEVICE(mode) (S_ISCHR(mode) || S_ISBLK(mode) || S_ISSOCK(mode) || S_ISFIFO(mode)) > What rsync commands are run for backup and for restore?
