I cannot comment on the issue of using the hardware RAID5 or not. However, I will say from experience that 1-disk virtual disks are bad idea. If you are doing that, you should put the disks in JBOD mode instead. Doing a 1-disk vdisk just puts an unnecessarily layer on top of disk I/O that gives a added failure mode for no purpose. -- Paul Raines (http://help.nmr.mgh.harvard.edu) On Mon, 27 Jul 2015 3:48am, lejeczek wrote: > what do you think? > > dump raid5? change each pdisk into vdisk exposing to OS and > instead run lvm raid5 on those vdisks with a cache device? > > thanks. > > _______________________________________________ > Linux-PowerEdge mailing list > [email protected] > https://lists.us.dell.com/mailman/listinfo/linux-poweredge > > > The information in this e-mail is intended only for the person to whom it is addressed.
