Expected Results: I expected to continue seeing information about the seven (7) partition entries associated with sdb. Additional info: Bug #107960 might be related, but it is marked for a different platform.
I am using kernel 2.4.19-openmosix7. Disk partition statistics are not available in this kernel too. The output from cat /proc/partitions is major minor #blocks name 3 64 58633344 hdb 3 65 514048 hdb1 3 66 1052257 hdb2 3 67 57062880 hdb3 Is there any patch available to fix this?
Don: What driver is used for the OS disk (/dev/sdb)? I'm assuming it's not on the qlogic driver or else upgrading it would be impossible with the system running. I'm asking because I'm unable to reproduce the problem here. Either it was fixed between 2.4.21-9.EL and the current sources I'm looking at or something weird is happening on your particular configuration that might be driver related.
It is an IBM ServeRAID volume. The driver is "isp". Version info in messages file: "IBM PCI ServeRAID 6.10.52 Build 563 <ServeRAID 4Lx>".
For what it is worth, both the IBM ServeRAID (ips driver) and the QLogic driver were updated in U2 (2.4.21-15.EL).
I expect to apply the U2 (and later) updates sometime in the next 4-6 weeks. I'll see if the problem still exists in the updated versions.
Any update on the results of testing U2 (or U3 or U4)?
