Light Posting

…may continue until Monday night. We’re in Stinson Beach for the weekend for a mini-vacation.

[Sunday-evening update]

We have no television here, other than a big screen with a DVD player, but I’m not sure I’d watch the president’s latest attack on the American people even if I did.

Back In LA

I was scheduled to come home this evening, but I had no other business in Seattle, and it turned out that Alaska lets you change flights same day for only $25, so I actually caught a 6 AM flight.

The bad news is that Fedora doesn’t seem to want to boot into the 4.2.5 kernel, in either Fedora 22 or Fedora 23 (I hoped upgrading to the latter would fix). It just bombs out and loops in a continual effort to boot. I had to revert to 4.1 to boot it. Not sure how to diagnose. I’ve seen hints that others are having similar problems in the Fedora fora, but no indication of what to do about it.

In Seattle

I had a long trip to get here, starting at 2:30 AM Central (two-hour bus ride from Columbia MO to St. Louis, two-hour plane ride to Charlotte, five-hour plane ride to Seattle), but I’m at the Museum of Flight, where I’ll be giving a talk and book signing tomorrow, for any Seattlites who want to show up. It’s $20 admission to the Spacefest, but it’s an opportunity for a signed book if you don’t have one.

I’ve never been here this time of year. I was surprised at the fall colors.

Back In Missouri

We drove back to Columbia today from west of Ann Arbor, after visiting family and friends up there. Initially took back roads, not the freeway, as we were trying to catch the last of the fall colors. I took Route 12 from south of Manchester all the way to Coldwater, through the Irish Hills which, despite having been raised in southeast Michigan, I’d never done, so if I had a bucket list, I’d cross that one off. Lovely (but looking a little depressed in off-season), and Michigan International Speedway was impressive from a distance.

From there we headed south to Fort Wayne, went east on 24 across northern Indiana. The plan was to go to Peoria, then continue down to Hannibal, but we realized that we would run out of light (and butt stamina in the car) long before we ran out of road, so we bailed not long after getting into Illinois, and took 57 south to 72, then 55 south to 270, then 370, then 70 west to Columbia. Got in about 7:30. Always nicer to gain an hour from the time change than losing it (we got into Michigan about 10 PM when we drove up Friday).

Anyway, here until Friday when I fly to Seattle for a book signing at the Museum of Flight on Saturday. Hope locals can make it.

Linux Problem

Can anyone figure out why /home is mounting read-only at boot?

Here’s my fstab:

# /etc/fstab
# Created by anaconda on Sat Apr 18 17:14:21 2015
#
# Accessible filesystems, by reference, are maintained under ‘/dev/disk’
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

Note that /dev/mapper/fedora_new–host–5-root is an SSD (as is boot), and /dev/mapper/fedora_new–host-home is a physical hard drive.

[Update a while later]

OK, clearly the disk is getting corrupted. I put in a file check option in the fstab, and it (temporarily) mounted it read-write at boot, but after working a while it became remounted read-only.

Any suggestions?

[Update a while later]

I had a spare 2T drive that I hooked up, and made it /home at boot (it was an old original, and the new drive was actually backup of it, so it had a lot of the data on it already). It’s working fine so far, except that when I copied my Gnome user configuration data over and rebooted, it decided that I wanted to have a Spanish desktop. I’ve changed the system settings to en_US, and even ‘localectl status’ give me:
System Locale: LANG=en_US
VC Keymap: us
X11 Layout: us

I can’t figure out where in the configuration files it’s getting the idea that I want to compute en Espanol, but while I can stumble along in it, it’s quite annoying.

[Wednesday-morning update]

OK, I determined that the language is changed in Gnome in “Settings,” but in the Spanish interface, that gets translated into “Configuracion,” so I was looking in the wrong place. So, now all is well, as far as I can tell. And as of this morning both the old and the new drive remain read/write. So still not sure what the problem was, but it seems to be a lot better now.

[Update a while later]

Wow. That drive had been causing problems I hadn’t even realized. My system had been running like molasses, with lots of runaway processes (like in Chrome). That’s completely disappeared. It’s like greased lightning now, even with several instances and many dozens of tabs open in Firefox.
