This read: You have 4 physical drives configured as one raid5 array. The array has three volumes (v0, v1, v2). These three volumes will be visible as three scsi devices in Linux. You can use for example lsblk or lsscsi to list them. Also, you may want to look physically for a battery backup unit (bbu). The software said there isn't one and that certainly could be a performance problem (as I would assume the controller turns off write-back caching). /Peter _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
