crash in dm-raid

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

I've got this crash in dm-raid when running the lvm testsuide (the failed 
test was shell/lvconvert-raid.sh ), but it is not reproducible, it doesn't 
crash when I re-run the test.

The crash happens when reading "conf->max_nr_stripes" because the pointer 
"conf" is invalid.
