pacman -Syu on my PogoPlugv4 this afternoon and noticed
locale-gen was being killed for some reason.
[user@tengu ~]$ sudo pacman -Syu :: Synchronizing package databases... ... :: Starting full system upgrade... ... ( 2/36) upgrading glibc Generating locales... en_US.UTF-8.../usr/bin/locale-gen: line 41: 17709 Killed localedef -i $input -c -f $charset -A /usr/share/locale/locale.alias $locale ( 3/36) upgrading libseccomp ...
Ran it manually and saw the same behavior. I could see something was in a bad
tmux would also refuse to reattach my session.
[user@tengu ~]$ sudo locale-gen Generating locales... en_US.UTF-8.../usr/bin/locale-gen: line 41: 18396 Killed localedef -i $input -c -f $charset -A /usr/share/locale/locale.alias $locale [user@tengu ~]$ tmux a tmux: invalid LC_ALL, LC_CTYPE or LANG
My hunch was
locale-gen was hitting the memory limit for the
PogoPlugv4, which doesn’t have much.
[user@tengu ~]$ free -m total used free shared buff/cache available Mem: 117 53 1 0 62 58
Nor was there any configured swap space.
[user@tengu ~]$ swapon --show [user@tengu ~]$ echo $? 0
The memory we can’t do anything about, but we can use swap space to give us some wiggle room. However, we run into more issues.
[root@tengu ~]$ fallocate -l 512M /swap fallocate: fallocate failed: Operation not supported [user@tengu ~]$ mount | grep sda /dev/sda1 on / type ext3 (rw,relatime,data=ordered)
I guess there’s an issue with
fallocate on F2FS or XFS, per
archlinux.org, but we’re running
man pages for
fallocate state “fallocate() is available on Linux since
kernel 2.6.23. Support is provided by glibc since version 2.10.” My versions
seem to be in line with that.
[user@tengu ~]$ uname -r 4.4.14-1-ARCH [user@tengu ~]$ /lib/libc.so.6 | grep release GNU C Library (GNU libc) stable release version 2.25, by Roland McGrath et al.
UPDATE: After some searching it turns out that
fallocate does not support
ext3, per this Bugzilla ticket. Guess this is what I get for using
Whatever, we can get around this by using
[root@tengu ~]$ dd if=/dev/zero of=/swap bs=1024 count=524288 524288+0 records in 524288+0 records out 536870912 bytes (537 MB, 512 MiB) copied, 23.8825 s, 22.5 MB/s [root@tengu ~]$ chmod 600 /swap [root@tengu ~]$ mkswap /swap Setting up swapspace version 1, size = 512 MiB (536866816 bytes) no label, UUID=a938d5b6-7113-4456-a633-7824b73d440d [root@tengu ~]$ swapon /swap
We can confirm the system now has a swap space.
[root@tengu ~]$ swapon --show NAME TYPE SIZE USED PRIO /swap file 512M 14.5M -1 [root@tengu ~]$ cat /proc/swaps Filename Type Size Used Priority /swap file 524284 14816 -1
locale-gen should have enough room to do what it needs to do.
[root@tengu ~]$ locale-gen Generating locales... en_US.UTF-8... done Generation complete.
tmux are happy.
