Hi, has anyone tried Open-iSCSI together with LVM and GFS (Global File System; Redhat open source). I have a cluster of 8 nodes (x86_64) where 4 nodes export an IDE disk via ietd. The IDE disks were labeled by LVM's pvcreate and build a volume group with a single logical volume. This volume group can be seen from all nodes (nodes which export their own IDE drive use the native block dev instead of the SCSI-dev imported with open-iscsi). I've compiled and installed redhat's GFS and CLVMD to use this distributed volume group on all nodes simultaneously. Creating and mounting the GFS volume works but the filesystem gets corrupted after some testing. Any ideas? Can I disable write-caching for the iSCSI-devices? Has anyone used iSCSI+GFS before?
iSCSI and GFS should work. It does when using GFS and the older iscsi driver. I have not tried it with open-iscsi though. I did not imagine there would be a problem.
Another problem: open-iscsi creates a new scsi-host for each imported disk. Is it possible to "bundle" the devices on a single host?
