Ext3 and RAID: silent data killers?Ext3 and RAID: silent data killers?Posted Sep 1, 2009 3:22 UTC (Tue) by zlynx (subscriber, #2285)In reply to: Ext3 and RAID: silent data killers? by flewellyn Parent article: Ext3 and RAID: silent data killers?
I think it's noteworthy.
Most people, myself included, expect a degraded RAID array to fail **only if another drive fails**. I do NOT expect losing 256KB of data because a single 4KB write failed.
And in fact, the array didn't lose it. It just can't tell which 4KB went bad, which it could if MD did good write-intent logging.
