Subject: [BUG]2.6.27.y some contents lost after writing to mmaped file
Date: Mon, 16 Nov 2009 11:38:57 +0800 [thread overview]
Message-ID: <2df346410911151938r1eb5c5e4q9930ac179d61ef01@mail.gmail.com> (raw)
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***
