Noam's idea about dmsetup was the solution. All the /dev/sdc partitions now mount with no problem., but I would like to ask if what I've done may have other side-effects. Below, I have 4 questions and I hope someone can answer them:
Here's a small section of /lib/modules/2.6.17-5mdv/modules.dep to show the lines I commented out. /lib/modules/2.6.17-5mdv/kernel/drivers/media/video/videodev.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/raid10.ko.gz: ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mirror.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-crypt.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/xor.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/raid6.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/xor.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/raid5.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/xor.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/raid1.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/raid0.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/multipath.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/linear.ko.gz: ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-zero.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-snapshot.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-round-robin.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-multipath.ko.gz ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-multipath.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-emc.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-multipath.ko.gz ##/lib/modules/2.6.17-5mdv/kernel/drivers/md/dm-mod.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/isdn/sc/sc.ko.gz: /lib/modules/2.6.17-5mdv/kernel/drivers/isdn/i4l/isdn.ko.gz /lib/modules/2.6.17-5mdv/kernel/drivers/net/slhc.ko.gz QUESTION #1 - I don't know if it was neccessary to comment them all, but the link Noam pointed to mentioned dm-mirrror and dm-mod so I commented all lines including either of them. Was that the right thing to do? QUESTION #2 - I booted twice (before and after making the above change) and compared dmesg. I found that before making the change, there were many lines of device-mapper errors and these were gone after making the change. So what were these error messages? device-mapper: 4.6.0-ioctl (2006-02-17) initialised: [EMAIL PROTECTED] device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table << lines repeated about 50 times >> device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table device-mapper: dm-linear: Device lookup failed device-mapper: error adding target to table I GOOGLEd and found several mentions of this problem, but not the solution. However, as I wrote above, after the changes to /lib/modules/2.6.17-5mdv/modules.dep, the error messages are gone. QUESTION #3 - While GOOGLing for this, I found some mentions of EVMS. I seem to remember that on a previous version of Mandriva I had disk-access problems until I un-installed EVMS. But now, I see that it's installed on my system. Do I need it and if so, why? QUESTION #4 - I still don't know the answers to the questions I asked in my previous post. >[EMAIL PROTECTED] solomon]# dmsetup deps >sdc8: 1 dependencies : (8, 32) >sdc14: 1 dependencies : (8, 32) >sdc7: 1 dependencies : (8, 32) >sdc13: 1 dependencies : (8, 32) >sdc6: 1 dependencies : (8, 32) >sdc12: 1 dependencies : (8, 32) >sdc5: 1 dependencies : (8, 32) >sdc11: 1 dependencies : (8, 32) >sdc10: 1 dependencies : (8, 32) >sdc9: 1 dependencies : (8, 32) > > >OK - I can't say I really understand what this means.
