2.2.19: Assertion failure in ext3_new_block() at balloc.c line 709



Red Hat 2.2.19-6.2.12
+ 0.0.7a
+ https://listman.redhat.com/pipermail/ext3-users/2001-November/002258.html
(not tuned in /proc yet)
+ journal 4MB on each fs
+ 6 ext3 fs on raid1 (hda+hdc)
+ 1 ext3 fs on another disk not on raid1 (hdd)

While untarring (tar zxf) a file that was on a ext3/raid1 onto hdd I got:
