I have come across two files, essentially untouched in years, on two
different ext3 filesystems on the same server, Gentoo AMD 64-bit with
kernel 2.6.22 and fsck version 1.40.2 currently, spontaneously
becoming supremely large:
Filesystem one
Inode 16257874, i_size is 18014398562775391, should be 53297152
Filesystem two
Inode 2121855, i_size is 35184386120704, should be 14032896.
Both were discovered during an ordinary backup operation (via EMC
Insiginia's Retrospect Linux client).
The backup runs daily and so one day, one file must have grew
spontaneously to this size and then on another day, it happened to
the second file, which is on a second filesystem. The backup attempt
generated repeated errors:
EXT3-fs warning (device dm-2): ext3_block_to_path: block > big
Both filesystems are running on different logical volumes, but
underlying that is are drbd network raid devices and underlying that
is a RAID 6-based SATA disk array.
