I just need to rebound on my initial question. I now want to install lvm2 with "cluster aware" tools (clvm). I want to use a lock on my lvm volumes which could be mount by multiple hosts (but only one at a time). |
| 25 |
I unmask clvm in the profile file of amd64. But when I install lvm2 with clvm use flag I don't have a useable clvm : |
| 26 |
|
| 27 |
iceage0 ~ # /etc/init.d/clvmd start |
| 28 |
* Caching service dependencies ... |
| 29 |
* Can't find service 'cman' needed by 'clvmd'; continuing... [ ok ] |
| 30 |
cman |
| 31 |
* ERROR: Some services needed are missing. Run |
| 32 |
* './clvmd broken' for a list of those |
| 33 |
* services. clvmd was not started. |
| 34 |
iceage0 ~ # /etc/init.d/clvmd status |
| 35 |
* status: stopped |
| 36 |
|
| 37 |
If I unmask cman, the result is : |
| 38 |
|
| 39 |
|
| 40 |
iceage0 ~ # emerge -pv lvm2 |
| 41 |
|
| 42 |
These are the packages that would be merged, in order: |
| 43 |
|
| 44 |
Calculating dependencies... done! |
| 45 |
|
| 46 |
emerge: there are no ebuilds to satisfy "=sys-cluster/cman-2*". |
| 47 |
(dependency required by "sys-fs/lvm2-2.02.51-r2" [ebuild]) |
| 48 |
(dependency required by "lvm2" [argument]) |
| 49 |
|
| 50 |
no cman-2 in portage... |
| 51 |
|
| 52 |
I have noticed that with clvm flag, configuration option for lvm2 are : |
| 53 |
* econf: updating LVM2.2.02.51/autoconf/config.sub with /usr/share/gnuconfig/config.sub |
| 54 |
./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --enable-readline --disable-selinux --enable-pkgconfig --libdir=/usr/lib64 --enable-dmeventd --enable-cmdlib --enable-applib --enable-fsadm --enable-static_link --with-mirrors=internal --with-snapshots=internal --with-lvm1=internal --with-cluster=internal --with-clvmd=none --with-pool=internal --sbindir=/sbin --with-staticdir=/sbin CLDFLAGS=-Wl,-O1 |
| 55 |
|
| 56 |
==> --with-clvmd=none is that normal? |

I have added a very "usefull" (for me) bug report for multipath-tools : |
| 62 |
http://bugs.gentoo.org/show_bug.cgi?id=293615 |
| 63 |
|
| 64 |
multipath hangs IOs instead of marking a volume as unusable... If I unmap a volume, multipath try changing the path all the time. So a raid1 on 2 volumes is not useable. |
