Hi all, I’m not sure, if this is the correct mailing list to make a suggestion for a new storage plugin (or an extension to the existing LVM-plugin). I have nodes with 12 disks each creating the drbdpool volume group. This could give me the opportunity to create LVMs in stripes to get a higher overall throughput. My very simple solution to get striped LVMs was to create a renamed copy of the lvm storage plugin (lvm12s.py), and simply modify the lvm creation command to self._cmd_create, "--stripes", "12", "--stripesize", "64", "-n", lv_name, "-L", str(size) + "k", instead of self._cmd_create, "-n", lv_name, "-L", str(size) + "k", and of course adding this to plugins.py and to the cluster config. I would suggest to implement a flexible method to create such striped LVMs. Best regards, Frank
