Hello: Thanks for your suggestion. I have upgraded the client kernel to ‘3.19.0-58-generic’. Now I can map the images, including format 1 and 2. Best Regards, WD From: Stefan Lissmats [mailto:stefan@xxxxxxxxxx]
Hello again!
I normally map with rbd map data03 -p block_data but your format should work. Mabye it's woth a try anyway? Is there any more explaining errors in dmesg after trying to map the image? Maybe there could be some clue what's happening there? Also is there any possibility to update the kernel? I see the kernel is quite old. In Ubuntu 14.04.4 the kernel version is now at 3.16.0-70-generic. Regards Stefan Från:
WD_Hwang@xxxxxxxxxxx [WD_Hwang@xxxxxxxxxxx] Hello: Sorry for that I forgot paste the results of image format 1. And I still cannot mount the format 1 or 2 block on Ubuntu 14.04 client, which the kernel is 3.13.0-85-generic

Hello! It doesn't look that you have created image format 1 images. I have created images in Jewel (10.2.0 and also som erlier releases) with the switch --image-format 1 and seems to work perfectly even if it's a depreciated
switch and causes warnings i have used it successfully with krbd and Ubuntu 14.04. The image format is going to stop workning i future releases as I understand så using this should probably just be used if you don't plan to use them
for production for an extended time. Regards Stefan Från: ceph-users
