Reboot the virtual machine and increase volume of the first hard drive by normal pvresize vda2<br><br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">dont expand volume group. then start to move other partitions to hard drive with space (pvmove /dev/vdb1 /dev/vda2). Repeat for all partitions to be removed. the problem with this pvmove is very slow. Remove migrated partition in lvm. If you still have free space in vda2 then do volume extend and resizing the file system. Migrating 500GB of partion took the whole night(12hrs). This can be worse for slow hard drives<br><br>--<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Lomayani<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br>--<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small">Lomayani<br></div><div class="gmail_default" style="font-family:verdana,sans-serif;font-size:small"><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Aug 12, 2016 at 6:30 PM, Lomayani S.
