I'm looking at updating to a 2.4.21 kernel on this machine due to the higher-performance Adaptec drivers of 2.4.19 forward. But before I can do this, I have to be able to successfully patch the 2.4.21 kernel to support mdp-style partitioned md devices, since the mdp RAID1 pair on this server contains important things like the mailboxes for our domains. I'm having a bit of trouble getting Neil's 2003-01-06 comprehensive patch to apply against a 2.4.21 pristine kernel tree - failed hunks in the parts that patch md.c. Looking back at the individual patches I originally used against 2.4.18 (patch-A-MdLocking, patch-l-RaidSplit, patch-m-MdPart, patch-n-MdMajor, and a modified patch-q-Fixes), even trying a dry run on the first of these patches (patch-A-MdLocking) produced failed hunks. I'm assuming that this is because at least some of Neil's patch work has been brought into the kernel source now (as i noticed reading the 2.4.21 changelog also), but short of some serious digging into the patches and comparing to the kernel source, I'm not sure what parts I would still need from add-on patches to get the mdp support with a 2.4.21 kernel. Can anyone offer any advice? Thanks in advance! vinnie
