Corruption can happen silently whenever anything on the _long_ path between platter and memory doesn't get copied right --- it can be software, or bad CPU, memory, cache, controller, cable, disk etc. If the drive is unable to read a sector, then yes, you'd expect e retry. But any other sort of corruption isn't detectable at the time so there's no retry involved. Corruption that hits the journal itself can cause an instant journal abort. One or two other cases can, too. Most cases where the drive is simply unable to read a block will _not_ cause an abort (EIO hitting the journal itself is an exception, though.) --Stephen _______________________________________________ Ext3-users@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/ext3-users
