I am trying to upgrade my system in order to use the device mapper and the LVM2. I am trying to upgrade to 2.4.25 my 2.4.20 system. On this system,there is already a LVM installation and I am using ext3 and jfs as my filesystems. It is not clear to me what patches are required and if the patches for filesystems should be applied or not. And are the 2.4.23 patches suitable for 2.4.25? For now, I compiled the Kernel and the dm library. However, I am trying to create the initrd and I am running into the following errors when trying to run the lvmcreate 2.4.25 command: Logical Volume Manager 1.0.8 by Heinz Mauelshagen 17/11/2003 lvmcreate_initrd -- make LVM initial ram disk /boot/initrd-lvm-2.4.25.gz lvmcreate_initrd -- finding required shared libraries lvmcreate_initrd -- stripping shared libraries lvmcreate_initrd -- calculating initrd filesystem parameters lvmcreate_initrd -- calculating loopback file size lvmcreate_initrd -- making loopback file (5004 kB) lvmcreate_initrd -- making ram disk filesystem (15197 inodes) mke2fs 1.18, 11-Nov-1999 for EXT2 FS 0.5b, 95/08/09 lvmcreate_initrd -- mounting ram disk filesystem lvmcreate_initrd -- creating new /etc/modules.conf lvmcreate_initrd -- creating new modules.dep depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/drivers/md/dm-mod.odepmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/drivers/scsi/ide-scsi.o depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/coda/coda.o depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/isofs/isofs.o depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/romfs/romfs.o depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/smbfs/smbfs.o lvmcreate_initrd -- ERROR running depmod So, I then ran the depmod -ae as following: [root@einstein boot]# depmod -ae 2.4.25 depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/drivers/md/dm-mod.odepmod: fsync_dev_lockfs depmod: mempool_free_slab depmod: mempool_alloc_slab depmod: unlockfs depmod: mempool_free depmod: mempool_alloc depmod: vcalloc depmod: mempool_resize depmod: mempool_destroy depmod: mempool_create depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/drivers/scsi/ide-scsi.o depmod: SELECT_DRIVE depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/coda/coda.o depmod: unlock_new_inode depmod: iget4_locked depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/isofs/isofs.o depmod: unlock_new_inode depmod: iget4_locked depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/romfs/romfs.o depmod: unlock_new_inode depmod: iget4_locked depmod: *** Unresolved symbols in /lib/modules/2.4.25/kernel/fs/smbfs/smbfs.o depmod: new_inode What is missing? -- ======================================= Daniel Savard =======================================
