Yes. It works pretty much the same way as it does on Intel. You use the mdadm package to create raid arrays, but it's done at the partition level. Option "t" in fdasd can be used to change the partition type to "Linux raid".
Typically, minidisk devices only have a single partition because it doesn't make much sense to have more (just have more minidisks), but in practice you can have up to three. -----Original Message----- From: Linux on 390 Port [mailto:[email protected]] On Behalf Of CHAPLIN, JAMES (CTR) Sent: Thursday, March 05, 2009 4:16 PM To: [email protected] Subject: [LINUX-390] Creating RAID Arrays on zLinux / zVM minidisks Okay, this is not real work, been working on my RHCT, and decided to test what I can do on a PC to the zLinux platform. I am trying to create a RAID-1 Array (two disks mirroring each other) in a zVM environment. I created two minidisks in zVM and am trying to format them on the zLinux side, using fdasd (instead of fdisk on the PC side). But I see no option to format "fd" the disks, with the interactive, it keeps asking for partition number (here is the display): (/root)#fdasd /dev/dasdk reading volume label ..: VOL1 reading vtoc ..........: ok Command action m print this menu p print the partition table n add a new partition d delete a partition v change volume serial t change partition type r re-create VTOC and delete all partitions u re-create VTOC re-using existing partition sizes s show mapping (partition number - data set name) q quit without saving changes w write table to disk and exit Command (m for help): t Disk /dev/dasdk: cylinders ............: 750 tracks per cylinder ..: 15 blocks per track .....: 12 bytes per block ......: 4096 volume label .........: VOL1 volume serial ........: 0X0205 max partitions .......: 3 ------------------------------- tracks ------------------------------- Device start end length Id System 2 11249 11248 unused change partition type partition id (use 0 to exit): Has anyone played with "software" RAID on the mainframe Linux?
