Hello, I'm new to OpenSolaris and ZFS so my apologies if my questions are naive!
I've got solaris express (b52) and a zfs mirror, but this command locks up my box within 5 seconds: % cmp first_4GB_file second_4GB_file It's not just these two 4GB files, any serious work in the filesystem (but I suspect the larger the file the worse it gets) bring the box to its knees. I've tried setting the maximum ARC size (seting c,p,c_max with mdb) but it doesn't help. Any other suggestions? As a newcomer my other questions are things like: 1) how can dtrace be used to debug this? (I know about truss but dtrace sounds more cool!) 2) how do I upgrade my kernel to the latest release in case it is already fixed? a) I'd like different entries in grub in case the new one is faulty! b) I don't want to prevent my box from using future patches, but the BFU warnings about this are quite scary 3) I don't know if this is related to zfs, but if this zfs filesystem is exported via samba and accessed from a laptop via a wireless router the performance drops to almost zero after about half a minute. Using snoop shows long periods without any packets, then short sporadic bursts.
