Yes, I think this looks like a bug, but like your previous problem it may have something to do with the interaction (buggy or otherwise) between polkit and systemctl.

Re: [gentoo-user] Permissions error on starting X.
Le 07/11/2018 à 04:59, YUE Daian a écrit : I got "setblabla error: cannot open /dev/tty0 (permission denied)". A possible solution without changing anything unnecessary is to run startx as "startx -- vt1". No need to change permission/ownership of anything. It is just required that the user is in "video" group. No "tty" or "input" needed. I presume it is because your user does not have access to TTY other than its login TTY. So if you log in by "tty1", just start X in "vt1". Hope that helps somehow. Thanks for this tip. This worked for me but adding the user to "input" group was also necessary. -- Hervé
[gentoo-user] Hard drive storage questions
Howdy to all, I have a interesting problem coming up. Currently, I have two 3TB drives for my /home mount point. A lot of this is videos but some pdf files and other documents as well plus a photo collection of family stuff etc. Filesystem Size Used Avail Use% Mounted on /dev/mapper/Home2-Home2 5.4T 3.7T 1.8T 68% /home I've got a little over 25% or so of usable space left. At that point or shortly thereafter, it could start causing some issues according to what I've read anyway. Either way, shortly after that, being full will certainly be a issue. I'm full up on my motherboard SATA ports. Even if I buy a larger drive or drives, I'd have to unplug one to move things over and likely repeat that a few times. I could do that and likely will have to anyway but I'm trying to think a little farther ahead. Currently I have the more important stuff backed up to a external single 6TB USB drive, previous thread on that. I'm trying to come up with a plan that allows me to grow easier and without having to worry about running out of motherboard based ports. I thought about a store bought enclosure with more than one hard drive that connects by ethernet. The ones I've found are fairly expensive. Doing it over USB concerns me for other reasons, USB isn't always that stable. So, internal isn't working out to well long term. Ethernet based is expensive, what I could find anyway. USB isn't that stable. I'm planning to upgrade my current system. Upgrade the CPU, memory and maybe even the video card as well. I thought about using a older spare motherboard, those removed components and building a mini system sort of thing. I could have one small drive for a OS and then add large drives for storage. Then I can access those from my main system, ethernet I would guess. Even then, I'd still be limited to the SATA ports on the MOBO at some point but it would be a ways into the future. So far tho, this is one of the better ideas. So far. Does anyone else have other ideas on how to do this? Some method that I've never heard of but doesn't cost a lot of money to do? Thanks in advance for any ideas. I can't think of anything else. ;-) If you need more info, let me know. Dale :-) :-)

Re: [gentoo-user] Hard drive storage questions
Firstly sorry about the top post, on the phone. I've had the same sort of thing happen to me. I was lucky to have available sata ports so bought two WD 8TB video archive drives and attached them to the MB. The card idea from the previous post is basically the same thing. In turn the archive drives will spin down after about 10 minutes, you will hear this happen and is a bit disconcerting the first couple of times, and use hardly any power. In turn if you need anything from the drives it takes just a few seconds to spin up again. In comparison to a small NAS thingy, I'm way ahead. No purchase of bare NAS, and much lower power consumption. Much higher data transfer rates as well. Having said that, I may have to buy a NAS in the long run as a backup for other purposes.

There are a few common approaches: * Find ways to cram a lot of drives on one host * Use a patchwork of NAS devices or improvised hosts sharing over samba/nfs/etc and end up with a mess of mount points. * Use a distributed FS Right now I'm mainly using the first approach, and I'm trying to move to the last. The middle option has never appealed to me. So, to do more of what you're doing in the most efficient way possible, I recommend finding used LSI HBA cards. These have mini-SAS ports on them, and one of these can be attached to a breakout cable that gets you 4 SATA ports. I just picked up two of these for $20 each on ebay (used) and they have 4 mini-SAS ports each, which is capacity for 16 SATA drives per card. Typically these have 4x or larger PCIe interfaces, so you'll need a large slot, or one with a cutout. You'd have to do the math but I suspect that if the card+MB supports PCIe 3.0 you're not losing much if you cram it into a smaller slot. If most of the drives are idle most of the time then that also demands less bandwidth. 16 fully busy hard drives obviously can put out a lot of data if reading sequentially. You can of course get more consumer-oriented SATA cards, but you're lucky to get 2-4 SATA ports on a card that runs you $30. The mini-SAS HBAs get you a LOT more drives per PCIe slot, and your PCIe slots are you main limiting factor assuming you have power and case space. Oh, and those HBA cards need to be flashed into "IT" mode - they're often sold this way, but if they support RAID you want to flash the IT firmware that just makes them into a bunch of standalone SATA slots. This is usually a PITA that involves DOS or whatever, but I have noticed some of the software needed in the Gentoo repo. If you go that route it is just like having a ton of SATA ports in your system - they just show up as sda...sdz and so on (no idea where it goes after that). Software-wise you just keep doing what you're already doing (though you should be seriously considering mdadm/zfs/btrfs/whatever at that point). That is the more traditional route. Now let me talk about distributed filesystems, which is the more scalable approach. I'm getting tired of being limited by SATA ports, and cases, and such. I'm also frustrated with some of zfs's inflexibility around removing drives. These are constraints that make upgrading painful, and often inefficient. Distributed filesystems offer a different solution. A distributed filesystem spreads its storage across many hosts, with an arbitrary number of drives per host (more or less). So, you can add more hosts, add more drives to a host, and so on. That means you're never forced to try to find a way to cram a few more drives in one host. The resulting filesystem appears as one gigantic filesystem (unless you want to split it up), which means no mess of nfs mountpoints and so on, and all the other headaches of nfs. Just as with RAID these support redundancy, except now you can lose entire hosts without issue. With many you can even tell it which PDU/rack/whatever each host is plugged into, and it will make sure you can lose all the hosts in one rack. You can also mount the filesystem on as many hosts as you want at the same time. They do tend to be a bit more complex. The big players can scale VERY large - thousands of drives easily. Everything seems to be moving towards Ceph/CephFS. If you were hosting a datacenter full of VMs/containers/etc I'd be telling you to host it on Ceph. However, for small scale (which you definitely are right now), I'm not thrilled with it. Due to the way it allocates data (hash-based) anytime anything changes you end up having to move all the data around in the cluster, and all the reports I've read suggests it doesn't perform all that great if you only have a few nodes. Ceph storage nodes are also RAM-hungry, and I want to run these on ARM to save power, and few ARM boards have that kind of RAM, and they're very expensive. Personally I'm working on deploying a cluster of a few nodes running LizardFS, which is basically a fork/derivative of MooseFS. While it won't scale nearly as well, below 100 nodes should be fine, and in particular it sounds like it works fairly well with only a few nodes. It has its pros and cons, but for my needs it should be sufficient. It also isn't RAM-hungry. I'm going to be testing it on some RockPro64s, with the LSI HBAs. I did note that Gentoo lacks a LizardFS client. I suspect I'll be looking to fix that - I'm sure the moosefs ebuild would be a good starting point. I'm probably going to be a whimp and run the storage nodes on Ubuntu or whatever upstream targets - they're basically appliances as far as I'm concerned. So, tho
[gentoo-user] Default USE flags for net-libs/webkit-gtk
Hi all, I wonder if there is a place to read previous discussions for a package/ebuild. Specifically, I am interested in the rationale behind having the "geolocation" flag on by default for net-libs/webkit-gtk. Currently on a desktop, having "geolocation" pulls in "geoclue" (which in turn pulls in "modemmanager" and so on), which is seemingly unnecessary in my case. I understand that these dependencies can be customised via /etc/portage/package.use/*, but I am also curious about the thinking behind net-libs/webkit-gtk having "geolocation" flag on by default. -- Yongming
