Hi,
I triggered a failure in an fs test with fsx-linux from ltp. It seems that fsx-linux failed at mmap->write sequence.
Tested kernel is 2.6.27.12 and 2.6.27.39 Tested file system: ext3, tmpfs. IMHO, it impacts all file systems.
Some fsx-linux log is:
READ BAD DATA: offset = 0x2771b, size = 0xa28e OFFSET GOOD BAD RANGE 0x287e0 0x35c9 0x15a9 0x80 operation# (mod 256) for the bad datamay be 21 ... 7828: 1257514978.306753 READ 0x23dba thru 0x25699 (0x18e0 bytes) 7829: 1257514978.306899 MAPWRITE 0x27eeb thru 0x2a516 (0x262c bytes) ******WWWW 7830: 1257514978.307504 READ 0x2771b thru 0x319a8 (0xa28e bytes) ***RRRR*** Correct content saved for comparison ...
