Hello the list, I was wondering if it were at all possible to have more than 256 block devices shared in a cluster. I'd like to export gnbd devices (10-15) with volume groups on top. There would be many lvs (up to 256) in each vg. Question is : how the device mapper will handle this on each cluster member ? I ran a basic test by creating more than 256 lvs in a single vg and device mapper did create devices twice with the same major/minor (wrapping after minor 255). Basically, that would mean I won't be able to share more than 256 lvs amongst the entire architecture. This limitation is far too low for me. I'd prefer hear about 10000+ ;-) I know this question is not directly related to the cluster project (except the clvm part), but since I have chances to find here some people with knowledge about large architectures, I try it anyway ... Thanks in advance for any tip. -- Sylvain COUTANT ADVISEO http://www.adviseo.fr/ http://www.open-sp.fr/ Tel: +33 (0)1 30 42 72 95 Fax: +33 (0)1 30 42 72 95 Gsm: +33 (0)6 30 79 26 33 sco@xxxxxxxxxx -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
