Re: [linux-lvm] I can't have the mirror_log mirrored, LVM complains "there is no suitable space"




Same result if done from a Debian LiveCD. If there are a lot of PEs why LVM complains it is not suitable, in my case it needs just 1 PE.

I used --alloc anywherebut it noticed the two mirror-logs were on the same disk, thing that I don't want of course...

Here's the proof fro the test --alloc anywhere

root debian:/home/user# lvs -a -o+devices
  LV                   VG           Attr     LSize Pool Origin Data%  Move Log       Copy%  Convert Devices
  root                 lvgrptstnlvm mwi-a-m- 6.00g                         root_mlog 100.00         root_mimage_0(0),root_mimage_1(0)
  [root_mimage_0]      lvgrptstnlvm iwi-aom- 6.00g                                                  /dev/sda1(0)

  [root_mlog]          lvgrptstnlvm mwa-aom- 4.00m                                   100.00         root_mlog_mimage_0(0),root_mlog_mimage_1(0)

  [root_mlog_mimage_1] lvgrptstnlvm iwi-aom- 4.00m                                                  /dev/sdb1(1537)

  /dev/sdb1              lvgrptstnlvm lvm2 a--  7.07g 1.06g                 1809  1538

Might this be for devs' attention?
