[ I'm new to the list, so feel free to point me at TFM ... ]
I have built a Linux 2.2.2 kernel with raid0145-19990309-2.2.3 and RAIDs
0 and 1 seem to work just fine (linear seems to need a chunksize!).
With the demise of "ckraid", how can I do I "check all is well" test ?
Also, how do I say "the duff disk of the mirror has been replaced, go
reconstruct it"
Can I still "manually dd the disk and tell the code to fix the superblock" ?
If I wasnt to test things, I can raisdtop, ZAP a partition, but cannot then
attempt a restart -- the only way I can do it is to reboot. Is there a way
to tell a running system to take a close look at a MD partition ?
Is there a way to manipulate *just* the superblock, e.g. to "correct"
a pure "dd"ed copy ?
Is there a way (preferably on a running system) to manipulate the RAID-1
info (e.g. announce a new disk, say that a bad disk is good once more) ?
Is there a way to add superblock info to an existing partition without ZAPping
it ? e.g. take a std partition, resize2fs it down a bit, add a SB, then set
up a second miiror disk, and get the system to copy it over, etc ...
To what should the chunksize be set for linear and RAID-1 disks ?
I know LVM is experimental and all that, but mkpv is included -- is there a
way to play with it ? When I try to load lvm.o I get:
/lib/modules/2.2.2/block/lvm.o: unresolved symbol del_mddev_mapping
/lib/modules/2.2.2/block/lvm.o: unresolved symbol md_hd_struct
/lib/modules/2.2.2/block/lvm.o: unresolved symbol add_mddev_mapping
I take that these are just not exportd :-(
