NFS v2 significantly faster for News expire
by sthaug＠nethelp.no 17 Mar '97

17 Mar '97

I switched our NetApp box to NFS v2 last night, and it *does* make a difference. It's a bit early to draw firm conclusions after only one expire run, but so far it looks like I cut my expire time with a whole hour. Nice! It's particularly noticeable during the 'fastrm' and 'renumber' phases. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

NFS v2 works okay, but statvfs won't tell me about inodes
by sthaug＠nethelp.no 17 Mar '97

17 Mar '97

Today I switched our F330 from NFS v3 to v2, since it's being used as a News spool and can't really do anything useful with the extra NFS v3 info. I got a nasty surprise when I found out that the Solaris 2.5.1 statvfs system call no longer returned number of inodes. In fact the fields u_long f_files; /* total # of file nodes (inodes) */ u_long f_ffree; /* total # of free file nodes */ u_long f_favail; /* # of free nodes avail to non-superuser */ are all set to 4294967295 (ie. -1) on return from statvfs. When I was using NFS v3, these fields had sensible values on return from the call. I can of course telnet to the NetApp and check the number of inodes directly, but I'd like to do it from the Solaris box which feeds the NetApp with news articles. Any good suggestions?

> how does one test for a shortage of NVRAM? Run 'sysstat 1'. If the writes are spaced out (there are intervals with no writes), you probably have enough NVRAM. If you have continuous writes, you probably need more NVRAM. Steinar Haug, Nethelp consulting, sthaug(a)nethelp.no

anyone here using a toaster to serve /var/spool/mail, including to a mail gateway machine (ie, not just for reading)? any comments thereon? particularly, what flavour of toaster, how configured, and roughly how many mail users.

I had plans to get an F220 to replace the Solstice ODS software-raid system we're using for mail now. We currently support 5700+ users (with a SS10 that has a 125mHz HyperSparc, and 3 pop/imap servers that mount the mail spool from the mailhub). Those plans got ixnayed (due to money concerns, feh!) and now we're looking at getting an ALR PPro 200mHz running Solaris x86 with one of ALR's recommended hardware raid cards. Definitely _definitely_ not my choice. *sigh* I didn't reply to the list 'cos this prolly wouldn't be very useful to them. I just thought I'd reply to give my support for the idea; I don't know how well it works, but I suspect that it will work *very* well!!! I'd go with an F220 at the minimum, unless you can afford the 330 already (they're trivial to upgrade, so buying an F220 is a cheaper alternative). Depending on how many users you're going to have, I'd also recommend getting 4mb NVRAM. -cgw- -- christopher williams 512.462.0999 fall seven times cgw(a)io.com sen sys eng fnord stand up eight In message <Pine.GSO.3.95.970226112407.19938G-100000@sproing>, you write: > anyone here using a toaster to serve /var/spool/mail, including to a mail > gateway machine (ie, not just for reading)? > > any comments thereon? particularly, what flavour of toaster, how > configured, and roughly how many mail users.

We're using a scheme similar to the qmail maildir format to store the mail (each message in a different file in the user's directory) so that we don't have to worry about file locking via NFS. All access is via POP. > any comments thereon? particularly, what flavour of toaster, how > configured, and roughly how many mail users. We are using a F540 with 256MB of cache and about 36GB of disk. We have two 500 Mhz Alphas and one PPro 200 as MX machines doing about 700,000 messages a day to over 100,000 mail users. Two 500 Mhz Alphas run pop daemons. Works like a dream. Drew -- "Joe, release me from your Kung-Fu grip." -- Stacy Lavelle
