> Subject: Re: [BBLISA] iSCSI - opinions / experiences? Thanks for all the responses! A number of you really know this stuff. While I'm familiar with CIFS/NFS; SAN, NAS, and iSCSI thing are way out of my comfort zone.
[disk on the end of an ethernet cable] Thanks Adam -- that description made makes perfect sense. It sounds like iSCSI is a viable option hooking up disks to a single machine. [NetApps] In a former professional life, we had one. I thought it was one of the most impressive pieces of hardware I'd ever seen. No reliability problems -- it just worked. Plus, the NetApp boot sequence is quite a show to watch -- on those rare occassions where you have to reboot the filer :) [Fedora NFS Headaches] Under light to moderate load, Fedora NFS is actually alright. Under heavier loads, I've found that it simply falls apart. Specifically, this seemed to tied to operations that access large number of inodes in rapid succession. Running `find' or `rm -rf' across a large nfs-mounted directory tree would produce hundreds or thousands of IO Errors (reported by the shell command). In a few cases, things were hung up so badly that we had to unmount the filesystem from the client, and restart the nfs server process to get it functional again. Samba on Fedora has been much more reliable. Although we've had to take some of our java and perl programs that read across samba mounts and put their open()'s in retry loop. (Periodocally, attempt #1 produces an IO Error, but attempt #2 is okay). This is Fedora <= 3. I don't know if things have improved with 4 & 5.
