Subject: [gentoo-user] LVM install fails to boot in 2006.0 with no-nptl/2.4 profile

1 I am in the process of installing Gentoo on an x86 from the 2006.0
2 installer CD using the 2.4 kernel profile. I created an LVM2 volume
3 group with logical volumes / filesystems for '/', '/usr', '/var',
4 '/opt', and '/home'. I had no problems mounting those filesystems and
5 then chrooting into that environment and performing the base install. I
6 compiled the 2.4.32-r4 kernel from gentoo-sources with no problems, and
7 created the initial ram disk by hand so that I could bring up the LVM2
8 volumes.
9
10 The problem I am having is when I boot into the initrd. I run vgscan
11 with no apparent problems, and it finds the volume group. When I run
12 'vgchange -ay <vgname>, I notice three problems:
13
14 1. There are entries in /dev/mapper/<vgname>-<lvname>, but no symlinks
15 in the form /dev/<vgname>/<lvname> --> /dev/mapper/<vgname>/<lvname>. I
16 run 'lvm vgmknodes' and it remedies this.
17
18 2. I see five complaints from 'vgchange -ay <vgname>' (one for each LV)
19 as follows:
20
21 on stderr: device-mapper: table ioctl failed: Invalid argument
22 on console (from dm-mod driver): device-mapper: one of name or uuid must
23 be supplied, cmd (12)
24
25 I ran vgchange under strace and here is the following snippet:
26
27 open("/dev/mapper/control", O_RDWR|O_LARGEFILE) = 9
28 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
29 address)
30 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
31 address)
32 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
33 address)
34 mlockall(MCL_CURRENT|MCL_FUTURE) = 0
35 brk(0x8936000) = 0x8936000
36 brk(0x8b1e000) = 0x8b1e000
37 getpriority(PRIO_PROCESS, 0) = 20
38 setpriority(PRIO_PROCESS, 0, -18) = 0
39 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
40 address)
41 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
42 address)
43 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
44 address)
45 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
46 address)
47 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
48 address)
49 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
50 address)
51 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
52 address)
53 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
54 address)
55 ioctl(9, DM_DEV_STATUS, 0x8109958) = -1 ENXIO (No such device or
56 address)
57 stat64("/dev/ide/host0/bus0/target0/lun0/part10", {st_mode=S_IFBLK|0600,
58 st_rdev=makedev(3, 10), ...}) = 0
59 stat64("/dev/ide/host0/bus0/target0/lun0/part11", {st_mode=S_IFBLK|0600,
60 st_rdev=makedev(3, 11), ...}) = 0
61 stat64("/dev/ide/host0/bus0/target0/lun0/part12", {st_mode=S_IFBLK|0600,
62 st_rdev=makedev(3, 12), ...}) = 0
63 ioctl(9, DM_DEV_CREATE, 0x8109958) = 0
64 ioctl(9, DM_TABLE_STATUS, 0x8109958) = -1 EINVAL (Invalid argument)
65 write(2, " ", 2) = 2
66 write(2, "device-mapper: table ioctl faile"..., 51) = 51
67 write(2, "\n", 1) = 1
68
69 3. When I try to mount the filesystem in that LV, it fails. I tried
70 with different filesystem types and it's the same result. From within
71 the 2.4 kernel based initrd, it fails. If I reboot into the 2.6 kernel
72 based installer environment, no problem.
73
74 This looks like an incompatibility between the lvm2 and/or device-mapper
75 library code and the kernel device-mapper code. Here are the versions
76 installed in the new installation and its initrd:
77
78 lvm2-2.02.05
79 device-mapper-1.02.03
80 gentoo-sources-2.4.32-r4
81
82 livecd 2.4 # ls -l /etc/make.profile
83 lrwxrwxrwx 1 root root 51 May 11 18:09 /etc/make.profile ->
84 /usr/portage/profiles/default-linux/x86/no-nptl/2.4
