The CentOS homepage states that ext4 is now a fully supported filesystem in 5.6. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
Steve, I'm managing machines with 30TB of storage for more then two years. And with good reporting and reaction we have never had to run fsck.
That's not the issue. The issue is rebuild-time. The longer it takes, the more likely is another failure in the array. With RAID6, this does not instantly kill your RAID, as with RAID5 - but I assume it will further decrease overall-performance and the rebuild-time will go up significantly - adding the the risk. Thus, it's generally advisable to do just use RAID10 (in this case, a thin-striped array of RAID1-arrays).
