Hi Tejun! Chris Frey ran into some problems with ext3 on UML. See: http://marc.info/?i=20100924041410.GA18040%20()%20foursquare%20!%20net
I can reproduce this issue with any file system on Linux >= 2.6.31. There seems to be a serious problem with the block layer on UML. Under high load any file system gets corrupted. The regression was most likely introduced with this three changes: 83096ebf1263b2c1ee5e653ba37d993d02e3eb7b (block: convert to pos and nr_sectors accessors) f81f2f7c9fee307e371f37424577d46f9eaf8692 (ubd: drop unnecessary rq->sector manipulation) 4d6c84d91d1a539ebc47d1a36a35e9390ba11fdc (ubd: cleanup completion path) Maybe only f81f2f7 is the bad one. They depend on each and I don't know all the internals... -- Cheers, //richard ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ User-mode-linux-devel mailing list User-mode-linux-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/user-mode-linux-devel
