fsck on reboot - guaranteed non-interactive?
by Trevor Cordes 27 Mar '19

27 Mar '19

I had a raid card failure on a box in Texas (thanks HP). They replaced the card, but now I need to fsck to ensure the fs's (which seem ok) are not messed up. Should be fine because they are journalled, but best to be sure. On the root fs obviously I'll have to force after reboot. But I want to make sure it doesn't stop to ask me anything, as no one is there, and for someone to look at it would take hours. Anyone know the best way to achieve that? Does fsck on reboot (using the magic file method) run with -y, or what? I found /etc/e2fsck.conf and man e2fsck.conf, but the only hints I got from there regarding non-prompting is possibly the "problems stanza", and possibly listing all/most problems manually and setting preen_ok=1 on each? Seems like a lot of work, especially given the warning in the docs in that section. And the docs don't list all the codes, so it looks like one has to dig in the source. I suppose I could be happy with an option that says auto-yes to all the minor/moderate problems but still can blowup waiting for console input for disastrous problems. What I don't want is for the thing to sit and prompt just because some dir is missing an inode or an extent isn't quite the right length. Thanks! P.S. here's what I've come up with so for for a conf file with options that sound useful to me: [options] broken_system_clock = 1 inode_count_fullmap = 1 log_dir = /boot/tec-fsck-logs log_dir_fallback = /root/tec-fsck-logs log_dir_wait = 1 log_filename = e2fsck-%N.%h.INFO.%D-%T max_count_problems = 65536 readahead_mem_pct = 5 report_verbose = 1

MeshCentral server
by Daulton 18 Mar '19

18 Mar '19

Hey guys, If some of you recall I was asking about solutions to remotely connect and manage systems that were Windows based. My requirements were that it was: 1) Not ridiculously expensive 2) Good security track record 3) Could connect to devices that were behind NAT I had mentioned MeshCentral and after evaluating my options I went with that. I wrote a how-to based on my testing for installing MeshCentral on OpenBSD. I include an example pf.conf as well. https://daulton.ca/meshcentral-server-on-openbsd/ -- Thanks, Daulton
