Hi, I'm also looking into cloning z/Linux images. I've been looking/using the available basic techniques, but I keep running into a problem. I suspect it has something to do with initrd.
If my boot disk is R/O, I receive these messages prior to init running: Loading module dasd_fba_mod ... Using /lib/modules/2.4.21-231-default/kernel/drivers/s390/block/dasd_fba_mod.o dasd(fba): FBA discipline initializing dasd(fba): /dev/dasdb ( 94: 4),[EMAIL PROTECTED]: 9336/10(CU:6310/80) 1024MB at(512 B/b lk) dasd(fba): /dev/dasde ( 94: 16),[EMAIL PROTECTED]: 9336/10(CU:6310/80) 9MB at(512 B/blk) dasdb:CMS1/ LXSWAP(MDSK): dasdb1 dasde:CMS1/ LXSWAP(MDSK): dasde1 dasd(fba): We are interested in: Dev 9336/00 @ CU 6310/00 dasd(fba): We are interested in: Dev 3370/00 @ CU 3880/00 dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: EXAMINE 24: Command Reject dete cted - fatal error dasd(eckd): Sense data: dasd(eckd):device 0150 on irq 10: I/O status report: dasd(eckd):in req: 0000000000ebef00 CS: 0x00 DS: 0x02 dasd(eckd):Failing CCW: 0000000000ebeff0 dasd(eckd):Sense(hex) 0- 7: 80 02 00 00 00 00 00 00 dasd(eckd):Sense(hex) 8-15: 00 00 00 00 00 00 00 00 dasd(eckd):Sense(hex) 16-23: 00 00 00 00 00 a2 0f 00 dasd(eckd):Sense(hex) 24-31: 00 00 40 e0 00 00 00 00 dasd(eckd):24 Byte: 0 MSG 0, no MSGb to SYSOP dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: (EXAMINE) ERP chain report for req: 0000000000ebef00 dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: 0000000000ebef00: c5c3d2c4 0000 0000 00000000 00000000 dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: 0000000000ebef10: 00000000 00eb ef00 00000000 00ebef00 dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: 0000000000ebef20: 00000000 00ef 7800 00000000 00ec0e00 dasd_erp(3990): /dev/dasda ( 94: 0),[EMAIL PROTECTED]: 0000000000ebef30: 00000000 00eb ... All the bind mounting and other magic happens *after* init runs. It looks like something is insisting that the boot disk be R/W during initrd. Any ideas?
