To find that out, issue the command: ls -l `find /lib/modules -name drbd.ko` and make sure all symlinks are there (no red-flashing link).

[CentOS] External USB disk devices cause high load
Hi On a CentOS 4.7 box running on older hardware when i plug an external flash disk or similar into the system the device shows up in dmesg but it is not usable. The load on the system starts to climb for no apparent reason. If i try to look at the partitions on the disk with fdisk it just hangs. If the device is removed the load remains high. Does anyone know what processes are responsible for USB as top is not really showing me much. thanks ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

You could ask on the open-iscsi list too. I thought if it treated each ip as a separate target portal on the initiator you would be able to connect to two "different" targets at the same time and let dm-multipath figure out it's the same disk. No? I think what is happening is open-iscsi (on 4) only recognizes the first target sent during a SendTargets request, but the first target in the list should always be the one on the current ip address of the portal, so if you list each ip address for discovery in theory it should discover the target for each ip. Now if Equalogics gives the same target list irrespective of the portal ip it's called on then I can see where the problem is. A tcpdump during login/discovery should show this easy. Just look at the sendtargets list for each portal in wireshark and if they are in the same order then there's your problem. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

No? You can do this, I'm sure of it. But the catch is this doesn't aggregate the links, even if you use round robin multipathing at any particular instant in time your only using one link. >From the docs from device mapper multipath on CentOS 5.2 Path Group: A grouping of paths. With DM-MP, only one path group--the active path group--receives I/O at any time. Within a path group, DM-MP selects which ready path should receive I/O in a round robin fashion. Path groups can be in various states (refer to "Path Group States"). So as far as I can see you can't aggregate paths in CentOS 5.2 multipath either for a single volume. The only way to use more than one path is to have more than one volume. You could set it up as active/passive and have each volume "prefer" a different path, or use round-robin and just know that at some points in time both volumes will be going down the same path. I suppose you could aggregate the volumes themselves using LVM or software RAID, to present a single file system to the OS that uses more than one path simultaneously depending on what data is being accessed. I think you'll probably find the software iSCSI has more serious performance bottlenecks before your able to max out a 1Gbps link anyways. nate ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There have been packages for php 5.2 in the Centos Testing repository for a while now.

If you have php 4.3, then you have centos4 most likely.
