Hi all, I am currently evaluating DRBD as a storage candidate for highly available storage in a virtualized environment. It seems like a very good alternative to expensive SAN/NAS. I was wondering how DRBD deals with the network block device deadlock problem. This problem (described here: http://lwn.net/Articles/195416/) can be summarized as follows: if the system runs short in memory, it will try to write dirty page to disk in order to free memory space. if the disk is a network block device, the dirty page write may need to allocate some other memory pages which is not possible since the solution to have more memory available was to write the dirty page to disk. If someone has some information about that problem I'am eager to read it. Thank you in advance. BR, Ivan -------------- next part -------------- An HTML attachment was scrubbed...
