In earlier coverage pitting ZFS against Linux kernel RAID, some readers had some concerns that we had missed some tricks for mdraid tuning. In particular, Louwrentiuswantedus to retest mdadm with bitmaps disabled, and targetnovemberthoughtthat perhaps XFS might outperform ext4. ...
We’ve found that Amazon’s network disk system (EBS) doesn’t support enough disk seeks per second, so having all of our working set in memory is extremely important. To get reasonable IO performance, we set up our EBS drives in a software RAID using mdadm. ...
So there is no single point of failure. So currently going towards linux raid with mdadm and lvm for ext4 filesystem on high density servers with 4 x CPUs. keeping it simple just as AWS does it. Sure i can use ZFS for backup server and NFS shares. Reaction...
