Hi all.... I'm sure this question has been asked before but I've been unable to find the solution in any of the archives. I had GFS up and running on a system running the 2.4.21-37.ELsmp (update 6) kernel and performed an up2date to get to the latest release, 2.4.21-47.ELsmp (update 8) Amongst the numerous RPM's that have been changed the GFS ones have been upgraded to the following: GFS-devel-6.0.2.34-2 GFS-modules-smp-6.0.2.34-2 GFS-6.0.2.34-2 The problems is that the various modules installed as part of the GFS-modules-smp-6.0.2.34-2 will not load. # depmod depmod: *** Unresolved symbols in /lib/modules/2.4.21-47.ELsmp/kernel/drivers/block/gnbd/gnbd.o depmod: *** Unresolved symbols in /lib/modules/2.4.21-47.ELsmp/kernel/drivers/block/gnbd/gnbd_serv.o depmod: *** Unresolved symbols in /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o depmod: *** Unresolved symbols in /lib/modules/2.4.21-47.ELsmp/kernel/fs/gfs/gfs.o depmod: *** Unresolved symbols in /lib/modules/2.4.21-47.ELsmp/kernel/fs/gfs_locking/lock_gulm/lock_gulm.o #insmod pool Using /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blk_dev_Rsmp_9d2a8367 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blkdev_put_Rsmp_aff0bb36 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blk_init_queue_Rsmp_e5c1537d /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol refile_buffer_Rsmp_accbf3d3 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol ll_rw_block_Rsmp_4c81d4ac /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol kernel_flag_cacheline_Rsmp_eb36899a /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol register_blkdev_Rsmp_b1e7aafd /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blkdev_get_Rsmp_e8f100cd /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blk_cleanup_queue_Rsmp_726de84b /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol getblk_Rsmp_55c716c5 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol __wait_on_buffer_Rsmp_5c764f29 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol bdget_Rsmp_4f5b15c0 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol del_gendisk_Rsmp_38acd99c /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol flush_signals_Rsmp_7f9054be /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol wake_up_process_Rsmp_67aed137 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol __brelse_Rsmp_15b3c770 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol add_gendisk_Rsmp_ab4f41e7 /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol get_gendisk_Rsmp_bbe6a7ad /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol blk_queue_make_request_Rsmp_8bc2cc9f /lib/modules/2.4.21-47.ELsmp/kernel/drivers/md/pool/pool.o: unresolved symbol generic_make_request_Rsmp_10b9064f My numerous attempts to get round this problem have all failed so if anyone has any ideas I'd be very grateful Thanks Paul McDowell Celera Genomics
