Did you run command 'fdasd -a /dev/dasdb' to create the partition? /dev/dasdb1 doesn't exist unless you run the command.

This is what I have fresh after my re-re-re-re-install. It seems "btrfs device add /dev/dasdb1 /" would be a good thing to do but I get message about dasdb1 not existing... sles12:~ # lsdasd Bus-ID Status Name Device Type BlkSz Size Blocks ============================================================================== 0.0.0250 active dasda 94:0 ECKD 4096 7042MB 1802880 0.0.0251 active dasdb 94:4 ECKD 4096 7042MB 1802880 sles12:~ # btrfs filesystem show Label: none uuid: d8b46146-19c1-48d8-b024-80547e728787 Total devices 1 FS bytes used 2.74GiB devid 1 size 5.71GiB used 3.53GiB path /dev/dasda3 Btrfs v3.16+20140829 sles12:~ # df -h Filesystem Size Used Avail Use% Mounted on /dev/dasda3 5.8G 3.0G 2.5G 55% / devtmpfs 439M 8.0K 439M 1% /dev tmpfs 446M 0 446M 0% /dev/shm tmpfs 446M 7.0M 439M 2% /run tmpfs 446M 0 446M 0% /sys/fs/cgroup /dev/dasda3 5.8G 3.0G 2.5G 55% /var/tmp /dev/dasda3 5.8G 3.0G 2.5G 55% /var/spool /dev/dasda3 5.8G 3.0G 2.5G 55% /var/opt /dev/dasda3 5.8G 3.0G 2.5G 55% /var/log /dev/dasda1 194M 24M 161M 13% /boot/zipl /dev/dasda3 5.8G 3.0G 2.5G 55% /var/lib/pgsql /dev/dasda3 5.8G 3.0G 2.5G 55% /var/lib/named /dev/dasda3 5.8G 3.0G 2.5G 55% /var/lib/mailman /dev/dasda3 5.8G 3.0G 2.5G 55% /usr/local /dev/dasda3 5.8G 3.0G 2.5G 55% /tmp /dev/dasda3 5.8G 3.0G 2.5G 55% /var/crash /dev/dasda3 5.8G 3.0G 2.5G 55% /srv /dev/dasda3 5.8G 3.0G 2.5G 55% /opt /dev/dasda3 5.8G 3.0G 2.5G 55% /home /dev/dasda3 5.8G 3.0G 2.5G 55% /boot/grub2/s390x-emu sles12:~ # On Thu, Apr 21, 2016 at 2:37 PM, Mark Post <mp...@suse.com> wrote: > >>> On 4/21/2016 at 05:33 PM, Grzegorz Powiedziuk > >>> <gpowiedz...@gmail.com> > wrote: > > then pvcreate, vgextend, lvextend and filesystem resize. > > No, we're trying to get him set up with LVM, just btrfs. > > > Mark Post > > ---------------------------------------------------------------------- > For LINUX-390 subscribe / signoff / archive access instructions, send > email to lists...@vm.marist.edu with the message: INFO LINUX-390 or > visit > http://www.marist.edu/htbin/wlvindex?LINUX-390 > ---------------------------------------------------------------------- > For more information on Linux on System z, visit > http://wiki.linuxvm.org/ > ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/ © 2016 Ensono, LP.
