https://community.hpe.com/t5/operating-system-linux/swap-mirror/m-p/2672431#M1219 My understanding is that you can't mirror swap on Linux. <BR /><BR />You can stripe swap for increased swap performance, however. Create multpile swap areas on multiple disks and set them all at the same priority in the /etc/fstab and the OS will stripe the information.<BR /> Wed, 27 Feb 2002 15:26:49 GMT Eric Ladner 2002-02-27T15:26:49Z https://community.hpe.com/t5/operating-system-linux/swap-mirror/m-p/2672430#M1218 which is the sense of mirror the swap?<BR />And which is the right configuration for the Mirror Write Cache and the Consistency Recovery mechanism??

I retract that. Seems that you can with kernel levels in the upper 2.3s or any 2.4.<BR /><BR />See <A href="http://www.linux.com/howto/Software-RAID-HOWTO-2.html#ss2.4" target="_blank">http://www.linux.com/howto/Software-RAID-HOWTO-2.html#ss2.4</A><BR /><BR />Although it's noted that this is not for performance reasons, only high availbility, and there is a caveat or two.
