Following the reports in [1] and [2], I discovered that I had missed two kernel options required by LVM2: CONFIG_UEVENT_HELPER_PATH="" CONFIG_DM_UEVENT=y Also, the system where I am doing my experiments is a virtual machine with almost nothing installed; therefore, I forgot to set USE=udev, and cryptsetup needs it. With those things out of the way, everything works as expected; there is no need for an explicit unit for the swap partition, and I can set it in fstab: /dev/mapper/swap none swap sw 0 0 I would like to use a label for the swap partition, but when the swap is encrypted systemd does mkswap in the partition without any parameter [3]. I could wrote a patch, I guess; but I don't think is worth it. Anyhow, I can get a Gentoo install with mdraid+LVM2+LUKS+systemd working as intended, and without hacks nor workarounds.

[gentoo-user] LVM2+mdraid5+LUKS+systemd (was Re: LVM2+mdraid+systemd)
OK, so I conducted another experiment, to see if I was able to make systemd *not* to work with an exotic combination of underlying storage. I did the following: - 4 drives, all of them in RAID5. - The resulting /dev/md127 was put in a Physical Volume, that in a Volume Group, and that split into 5 Logical Volumes: 1. /boot (unnecessary, but why not) 2. swap 3. / (root) 4. /usr 5. /home - The /home partition was encrypted, and so was the swap. Everything works, but now I did had to do something not intuitive. First the intuitive changes from my previous experiment: 1. I had to put this in /etc/default/grub: GRUB_PRELOAD_MODULES="lvm mdraid1x" Basically that's it. The partitions again use labels, so I didn't had to touch fstab, except for the not intuitive change. The problem, that I believe Stefan and Frank hinted, is that the encrypted swap did not activated properly, sometimes resulting in huge boot times (in the order of 1 minute). But only if you specify the swap partition in fstab. The problem is, I think, that systemd tries to activate as soon as possible the swap partitions, even before systemd-cryptsetup activates the devices in /dev/mapper. The solution is to move the swap partition from fstab, and create a system unit for it which has to wait until systemd-cryptsetup does its job: lvm ~ # cat /etc/systemd/system/dev-disk-by\\x2did-dm\\x2dname\\x2dswap.swap [Unit] After=systemd-cryptsetup@swap.service [Swap] What=/dev/disk/by-id/dm-name-swap lvm ~ # cat /etc/crypttab home /dev/vg/vol5 swap /dev/vg/vol2 /dev/urandom swap lvm ~ # cat /etc/fstab LABEL=Boot /boot ext2 acl,noatime 0 2 LABEL=Root / ext4 acl,noatime 0 1 LABEL=User /usr ext4 acl,noatime 0 2 LABEL=Home /home ext4 acl,noatime 0 2 shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 tmpfs /tmp tmpfs defaults,nosuid,size=100% 0 0 Everything works; at boot time systemd asks for the passphrase for /home, and after a timeout continues the boot without mounting it.

Re: [gentoo-user] re: alternating between wired and wireless interfaces
Just thought I'd give the other popular alternative of the Redhat backed NetworkManager. Also, if you don't wait for the interface to come up I don't think the service can bind to the interface (and it obviously can't bind to an IP). Probably not an issue for ssh but possibly one for MySQL or Apache.

Re: [gentoo-user] Comparing RAID5/6 rebuild times, SATA vs SAS vs SSD
On 2013-09-20 6:43 PM, Paul Hartman wrote: A couple weeks ago one of the drives died. I hot-swap replaced it with a new one (with no down-time) and the rebuild took exactly 10 hours. Under normal operation, the speed of the array for contiguous read/writes is about 600MB/sec, which is faster than my SSD (single drive, not RAIDed). Thanks... But... RAID read/writes under normal operating conditions has nothing whatsoever to do with REBUILD speeds/times. Again, the reason I'm interested in this is, if the rebuild times are 'blindingly fast' (as compared to the times for SATA or even fast SAS drives - ie, 1 hour vs your 10 hours)), then maybe a RAID6 with SSDs is back in the realm of doable, since you don't lose 50% of available storage with RAID6...

As long as ZFS can 'see' the block device comes time for it to mount the pool and all 'child' datasets (or zvols), all should be well.

Does 'rfkill list' confirm that the wlan0 hardware is switched on?

[gentoo-user] wifi connection problem
After moving from one location to another, changing ISPs from Metrocast to
Comcast, we're having connectivity issues. But let me just state the problem
with the wife's PC, peter. (My laptop, baruch, works with a static IP using
wicd...nothing has worked using DHCP in Gentoo since moving to Comcast.)
It can connect with a wire, but not wireless, using /etc/conf.d/net and
wpa_supplicant.conf

Yeh, same advice here, try wicd first. If you don't want a GUI (or you don't have corresponding UI toolkits installed), there's also the option to configure and use wicd via the ncurses interface.

I am running gentoo on a laptop, as you have rightly guessed. It was suggested to me by somebody else on this list that using Wicd might be a viable option.

In the default configuration, network-dependent services only start if all network services are up and running. This is most annyoing for laptop users who might not be connected at all at times. The solution is to not have network services depend on all interfaces. Please look at /etc/rc.conf for rc_depend_strict; if you set it to "NO", then services are satisfied with any net.* service, even net.lo.

I've noticed that when I am scrolling up/down a page in Firefox, or scrolling up/down an email body in Thunderbird, it's not seamless. Not sure how to best describe what I mean by 'not seamless'. It's kind of wavy. The text is. Is this kind of behaviour a result of something missing in the kernel I'm using, or in the graphics driver, or something else.

That did it. box0=; grep sources /var/lib/portage/world sys-kernel/gentoo-sources sys-kernel/gentoo-sources:3.8.13 Once I decide I no longer need 'gentoo-sources-3.8.13', would it be enough just to remove the corresponding line from '/var/lib/portage/world', or is there a better way of doing it? Thanks.

The unmerge process leaves any temporary files from the compilation process intact (unless you manually delete them). If you later reemerge that version you'll start right of where you were. signature.asc Description: Digital signature

No, this it the wrong file. the file /var/lib/portage/world is THE world set, it contains all packages you emerged manually (and with --noreplace). The file /var/lib/portage/world_sets can contain the name of other sets that should be included into the world. > > box0 src # emerge --noreplace sys-kernel/gentoo-sources-3.8.13 > !!!

[gentoo-user] re: emerge --depclean [gentoo-sources]
emerge --depclean wants to remove the gentoo-sources for my old kernel [sys-kernel/gentoo-sources-3.8.13] which I want to hang on to for the time being. Is there a way to instruct emerge not to remove them? emerge(1) Packages that are part of the world set will always be kept. They can be manually added to this set with emerge --noreplace . If I understood the instruction above, 'emerge --noreplace sys-kernel/gentoo-sources-3.8.13' should have added 'gentoo-sources' to /var/lib/portage/world_sets, which it didn't seem to do. box0 src # emerge --noreplace sys-kernel/gentoo-sources-3.8.13 !!! 'sys-kernel/gentoo-sources-3.8.13' is not a valid package atom. !!! Please check ebuild(5) for full details. box0=; ls -l `pwd`/world* -rw-r--r-- 1 root portage 920 Sep 20 20:45 /var/lib/portage/world -rw-r--r-- 1 root portage 0 Sep 20 20:45 /var/lib/portage/world_sets Or is it a matter of defining something like this: CONFIG_PROTECT_MASK="/usr/src/linux-3.8.13-gentoo" in /etc/portage/make.conf? Any pointers would be much appreciated.
