Backup Central

I'm getting this huge set of error messages, most of which I don't
understand. There's a "read-only file system" line which seems to be
intelligible but I have no idea why it appears. I'm plugging in my
external HDD the same way I did last time, when rdiff-backup ran fine,
and the 'mount' command shows this for the backup file system,
"/dev/sdb1 on /media/b080d187-ad00-4b4a-9721-fcbe5e839827 type ext3
(rw,nosuid,nodev,uhelper=devkit)"--ie, it's presumably mounted 'rw'.

Here's the whole set of messages (I tried to run the rdiff-backup twice
and got slightly different results, but no success.) Hopefully someone
can help me on this.

Well I rebooted and then it ran fine. Does that mean it is _necessary_
to run rdiff-backup with a "clean" boot, or does anyone have some other
explanation for the errors I got?

Thanks

"/dev/sdb1 on /media/b080d187-ad00-4b4a-9721-fcbe5e839827 type ext3
(rw,nosuid,nodev,uhelper=devkit)"--ie, it's presumably mounted 'rw'.

Here's the whole set of messages (I tried to run the rdiff-backup twice
and got slightly different results, but no success.) Hopefully someone
can help me on this.
[...]

I had this kind of "read-only file system" errors recently. Then I
noticed that the 3.5" external USB drive was not plugged in properly,
and had lost power during the backup.

Maybe that's what happened during your backup? Or the connection to the
drive was lost in some other way?

Patrick.

Well I rebooted and then it ran fine. Does that mean it is _necessary_

explanation for the errors I got?

ListError home/eric/.gtk-bookmarks/.gvfs [Errno 13] Permission denied:


When the reboot fixed this, the problem is the ".gvfs" virtual
filesystem - the reboot got rid of it (I guess it will be automatically
mounted again when you do something with you bookmarks). This virtual
filesystem can not even be accessed as root, that's why you get the
error above.

Add --exclude-other-filesystems to the command line to skip those
virtual filesystems, the contents are not meant to be backed up, anyway.

I hope I'm not teaching you to suck eggs, but filesystems are often
remounted read-only automatically if the OS encounters errors while
writing. It sounds like that happened to your drive mid-backup, and that's
why rebooting fixed it – it got mounted as normal as part of the boot
process.

It sounds like your backup drive is becoming more unreliable (which is a
less dramatic way of saying "could be about to fail"), which is why it
happened at different points in your backup. USB also has limits to the
amount of data it can simultaneously transfer, so if you're doing a lot of
other USB-centric stuff at the same time as your backup this could also be
a problem.

If you have a second system you can plug your external drive into, you
could do some tests to confirm it is the drive that's causing problems.


Hope this helps,

.gvfs is a fuse mount point. Only the user that mounted it has permission to access it. Not even root does.

So, while your point is valid for standard filesystems, there's no need to scare for this instance.

Sure, but I don't think the .gvfs error is related to the eventual failure
of the backup. Instead, it's a result of Eric backing up his home
directory (which includes a .gvfs directory that has the permissions set
as you describe). The traceback doesn't include a log of what file
rdiff-backup was attempting to back up, but the syslog excerpt given by
the OP includes a "journal commit I/O error" and incorrect permissions
wouldn't result in a previously writable filesystem being remounted as
read-only.

The discussion is getting interesting. Thanks.

In previous rdiff backups, the .gvfs file was simply ignored. So I don't
think this could have caused the problem.

External HDD could be the problem. I had serious trouble with a WD
Passport because of some crap on it that couldn't be removed and
basically wouldn't let me use it with Linux (and WD was very snotty
about not providing Linux support for their HDDs). Now I'm using a USB
Toshiba drive (same small size as Passport). I may need to use my
Y-cable to get appropriate and consistent power for it?

I didn't notice this one,
Message from syslogd < at > linux-7fva at Jun 21 06:32:23 ...
kernel:[121311.947209] journal commit I/O error
that's some more serious problem.
You should have more info saved in the syslog file.

Passport because of some crap on it that couldn't be removed and

Toshiba drive (same small size as Passport). I may need to use my
Y-cable to get appropriate and consistent power for it?

While I don't know about the black magic of Y-cables, I'd take a look at
the smart data of the drive, esp. Current_Pending_Sector and
Reallocated_Sector_Ct . If it has more than a few bad sectors I'd try to
RMA the drive.
You may need additional switches for smartctl to get it to work over
USB:
http://sourceforge.net/apps/trac/smartmontools/wiki/Supported_USB-Devices (and
it may not work at all, unfortuanately, though there are some Toshibas
in the list)
