Hello List, I am using lvm version 2.02.177(2), tried to create a mirrored LV, but failed with the errors, tb0307-nd1:~ # pvs PV VG Fmt Attr PSize PFree /dev/vdb cluster-vg2 lvm2 a-- 40.00g 36.00g /dev/vdc cluster-vg2 lvm2 a-- 40.00g 40.00g tb0307-nd1:~ # vgs VG #PV #LV #SN Attr VSize VFree cluster-vg2 2 1 0 wz--nc 79.99g 75.99g tb0307-nd1:~ # lvs <<== a linear LV can be created LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert test-lv cluster-vg2 -wi-a----- 4.00g tb0307-nd1:~ # lvcreate --type mirror -m1 -L 500m -n my-lv cluster-vg2 Shared cluster mirrors are not available. <<== failed to create a mirrored LV
Clustered old mirror needs 'cmirrord' to be installed and running.
Could you help to take a look at this problem? from lvcreate man page, the mirrored LV is supported by lvcreate. my lvm2 version/configuration is as below, tb0307-nd1:~ # lvm version LVM version: 2.02.177(2) (2017-12-18) Library version: 1.03.01 (2017-12-18) Driver version: 4.37.0 Configuration: ./configure --host=x86_64-suse-linux-gnu --build=x86_64-suse-linux-gnu --program-prefix= --disable-dependency-tracking --prefix=/usr --exec-prefix=/usr --bindir=/usr/bin --sbindir=/usr/sbin --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/lib --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --disable-dependency-tracking --enable-dmeventd --enable-cmdlib --enable-udev_rules --enable-udev_sync --with-udev-prefix=/usr/ --enable-selinux --enable-pkgconfig --with-usrlibdir=/usr/lib64 --with-usrsbindir=/usr/sbin --with-default-dm-run-dir=/run --with-tmpfilesdir=/usr/lib/tmpfiles.d --with-thin=internal --with-device-gid=6 --with-device-mode=0640 --with-device-uid=0 --with-dmeve ntd-path=/usr/sbin/dmeventd --with-thin-check=/usr/sbin/thin_check --with-thin-dump=/usr/sbin/thin_dump --with-thin-repair=/usr/sbin/thin_repair --enable-applib --enable-blkid_wiping --enable-cmdlib --enable-lvmetad --enable-lvmpolld --enable-realtime --with-cache=internal --with-default-locking-dir=/run/lock/lvm --with-default-pid-dir=/run --with-default-run-dir=/run/lvm tb0307-nd1:~ #
