Hi, Is it possible to mount drbd on slave machines as read-only. I have tried it but got following errors: [root at clu2 /]# mount /dev/drbd0 /mnt /dev/drbd0: Input/output error mount: block device /dev/drbd0 is write-protected, mounting read-only /dev/drbd0: Input/output error mount: /dev/drbd0 already mounted or /mnt busy I have 2 drbd machines (clu1 and clu2) .. Clu1 mount drbd0 and writes it but at the same time I want to mount it on clu2. I have found out that there is nbd and enbd projects but these mounts directly (in my situation) clu1's shared partition. I want to setup slave mysql servers that mounts drbd partiotion as read-only with caching disabled. Thus I will offload my master mysql server from replication burden and I am living problems about replication WRITE operations on mysql Master can be so high that replication on slaves lag. I thought using drbd I will always have the same data as master and replication will be handled in kernel not on application.. Best Regards. -- Omer Faruk Sen http://www.faruk.net
