Hi all,
I perform a nightly snapshot of /home to a USB attached drive scheduled
via cron. The system is CentOS 5.2 and only gets attached to the
internet periodically for updates, otherwise serves as a samba server to
about 20 Windows clients.
The rsync command being used is:
rsync -av --delete /home/ /media/bkup320G/
and has been working well until a few days ago.
Starting with a few days ago, my nightly rsync/cron emails included some
errors as shown here:
rsync: mkstemp
"/media/bkup320G/cprcvs/c/Projects/WindowApps/DLL/HMRControlDLL/.CMDSettingsDialog.cpp,v.I5QnaM"
failed: Read-only file system (30)
rsync: failed to set times on
"/media/bkup320G/cprcvs/c/Projects/WindowApps/DLL/PSIControlDLL":
Read-only file system (30)
There are multiple issuances of these errors for different files....some
files are written just fine. Where there are errors, its always the
same Read-only file system (30).
Output of df and mount show all filesystems as (rw):

Googling has not been fruitful in this issue and I'm curious what might
be the issue. I'd originally thought it might be drive failure on the
external (destination) drive, but changing that produced the same errors.
We typically backup about 165G overnight, so initial write to a new
drive takes a LONG time.
Any pointers or suggestions would be greatly appreciated.
TIA,
-Ray
