New: System freeze while rsyncing whole system from ext4 to ext4 via USB 2.0
https://bugzilla.kernel.org/show_bug.cgi?id=29662
Summary: System freeze while rsyncing whole system from ext4 to
ext4 via USB 2.0
Product: File System
Version: 2.5
Kernel Version: 2.6.38-rc6
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: ext4
AssignedTo: [email protected]
ReportedBy: [email protected]
Regression: Yes
This morning I rsynced my system to an USB HDD via some scripts utilizing rsync. The machine froze when a big file was transfered (updated on the backup device). The host as well as the backup use ext4.
My machine froze with no logs at all. The system just stalled and anything using the host disk was unusable. No new shell, no closing of running apps (probably due to stalled config writes on exit).
acpid shutdown via power button worked but the init scripts suffered a lot of problems. Finally (after some minutes) the disk could be unmounted by the init script and the machine powered off.
I don't know what I could do to repeat that problem. I was unable to ssh in and switch to vt1 as well.

--- Comment #2 from Marc <[email protected]> 2011-02-23 07:17:09 --- OK, I retested some more and think this was related to #29022. When no X is running there were no probs.
