Re: [gentoo-user] how to move overlays to a new storage location

Store your own custom overlays in PORTDIR_OVERLAY in /etc/make.conf layman maintains it's own list of overlays and locations, so you must source /var/portage/local/layman/make.conf in /etc/make.conf and defined the overall storage area for layman overlays in /etc/layman/layman.cfg -- alan dot mckinnon at gmail dot com

Think of the USE flags this and that as shortcuts to ./configure --enable-this --disable-that. So, for example mplayer could be a binary which can take advantage (or not) of SSSE3 and is designed to run only (or not) on core2. P.S.

Maxim That you run out of inodes doesn't mean that you run out of physical (or logical) space on your disk. It just means that you run out of what you could call file descriptors. There is exactly one inode per file which stores meta information about this file. Ext2-4 have a fixed amount of inodes set when you format the partition. Reiserfs and JFS create them on the fly and therefore don't have problems with running out of inodes or wasting space on unused ones. Most likely you have a bunch of very small files on our disk, for example the portage tree. These don't consume much space but a lot of inodes. My advice: Save everything to another disk and then reformat the partition with a higher amount of inodes. If you use ext2, format it with mke2fs -N 732960 /dev/sda2 This will create a file system with three times as many indoes as you had before. Hope this helps.

Not the same thing. -march= instructs gcc to produce a binary designed to run only on the given CPU architecture, while USE flags instruct the build system to include or not support for a given feature ... Actually, I _think_ in mplayer the difference is that the USE flags enable the use of hand-written assembler code which takes advantage of the MMX or whatever. I'm not 100% sure about this at all, but what's the difference in the architectures of the Pentium 2 the Pentium 3, if not for the support for SSE? (and / or whatever) Sure they are designed differently, but surely the instruction sets of all 32-bit processors from the earliest Pentiums even to Core Duos (not Core2s) are all basically x86. Some have these extended instruction sets (EIS, I think you called them earlier in the thread) and those are the additions from one generation to the next. So if you choose -march=pentium3 it will not run on a Pentium 2 because Pentium 2s do not have SSSE, and it's the *compiler* that added the code that utilises SSE. I believe that mplayer is one of those exceptional packages which uses some assembler optimisations. These don't make any sense for most programs, because it takes too much time to write much maintenance is loads of hassle, and assembler will make little difference. Most programs are one minute opening a new window, and the next minute are waiting for the mail server to reply and are doing lots of different tasks which are not worth hand optimising. But once mplayer has started decoding a video, then it's doing the same thing time time again, decoding each frame of the picture - it does exactly the same thing 25 times per second for an hour or two at a time, so that may be worth optimising for if the compiler is found to be less clever than someone like John Carmack. I'm not absolutely sure that the USE flags enable hand-written assembler code, but what I do know is that: 1) ASM stands for assembler. See http://en.wikipedia.org/wiki/Asm 2) Google mplayer asm returns a bunch of hits. 3) MMX was marketed as MultiMedia eXtension 4) mplayer is a multimedia player. 5) MMX doesn't have floating point support, but SSE adds that and has dedicated functions for multiplying floating point numbers [1], which is just the sort of thing that one are useful in decoding mpegs playing back video.

Yup, two configs, two init scripts, two instances. Just like apache. However, it's an e-commerce site so one must state the obvious: You must be out of your mind running an ecommerce site on the same machine as other php vhosts. Please give me the URL so I know never to buy there - I have no way of knowing what those vhosts are, who the webmaster is and how secure they are. Is the fear that one of these apache vhosts installations will be compromised and then the ecommerce/payment website will get hacked from the inside? Yes. You do not ever want people's credit card details exposed or stolen. You need to take extraordinary efforts or customers will not trust you. Any thought you ever have along the lines of I don't need to do thing X as that will not happen - beware, that's the very time that Murphy makes X happen... So I recommend option 4: Pony up the money for server #2 Hmm, yes that's what I was trying to avoid. ;-) Would running complete virtual servers to achieve separation be any/much better? It's almost as good as separate hardware, especially if you have a good virtual machine system that gives you complete separation of network interfaces - either physical or virtual. If the box can handle the load, I say go with this approach. You have to have an enormous site with heaps of users to outrun an average modern server -- alan dot mckinnon at gmail dot com

He decides to run the two sites on different machines, one for MickBlog.org and one for MicrophoneShoppe.com. If MickBlog is insecure, what makes you think he will administer MicrophoneShoppe any more securely? If Mick decides to run both sites on the same machine, served by the same MySQL sever Apache instances, surely he can set permissions in such a way that MickBlog.org is unable to access the data of MicrophoneShoppe.com? I don't know all the details, but (at least) the SQL server should be able to host multiple databases, each with different permissions; thus someone obtaining the admin WordPress password for MickBlog.org may be able to edit the blog posts on that site, but they shouldn't be able to access the shop's DB (which should be separate (a separate MySQL user?) and secured with a different password). My biggest reservation to my the thoughts I've outlined above (and I'm by no means saying those are sound, either) is that PHP is mentioned, and I've heard that's not the most secure language. Is that also your concern? There are loads of web hosting companies out there that offer ecommerce options, and I'd have thought that some of them are $30/year deals which are run in vhosts and shared databases just like this. So I'm inclined to imagine that this must be possible with _some_ level of security. Clearly, yes, the best option is to isolate things as much as possible, but the site's income might not justify the expense of a dedicated server at present - does that render secure ecommerce truly impossible?

Re: [gentoo-user] [ot] no more inodes

Won't that copy over the extraneous inodes? You appear to not understand what an inode is. The inode IS THE FILE. It's a specially formatted block on disk, the filesystem knows how to interpret it, and it contains all known information (except one piece) about the file - as in, everything that ls can display. The missing bit of information is the name you call it by, that is stored in the directory (which is really just a special file and contains file names and their corresponding inode numbers - this is how the fs driver finds files). When you copy a file, the inode is read and a new one initialized in the new location. Then the disk blocks are read from the original and copied to the destination. As the destination does this, the fs driver knows how to keep it's inode accounting intact. So, there is no such thing as an extraneous inode. It's either being used (and thus gets copied) or it is not used (and does not get copied). You cannot copy a file without copying it's inode, and you cannot copy an inode without copying the file (special exception - files of zero length). This will create a file system with three times as many indoes as you had before. Is 3x enough? I haven't even gotten off the ground yet, 28 lines in /var/db/pkg/world and my alotted inodes have been already used up? No gnome, kde, gimp, office etc etc. You will need approx 500,000 inodes on an average machine total, split that up amongst your mounted volumes as appropriate. Use find -x | wc on an existing machine per mount point to get a rough idea of the scale. FWIW, I thought I'd chroot in and do an emerge -C mozilla-firefox but it hadn't even been installed yet! It choked on dev-java/jdk. So, did emerge mozilla-firefox. Same thing: IOError: [Errno 28] No space left on device: '/var/db/pkg/dev-java/-MERGING-sun-jdk-1.6.0.13/CFLAGS' Well, what did you expect? You have used up all the index entries for files, and you are trying to create more files. What else could it do apart from fail? Log onto the machine and delete some stuff. Then try unmerge to free up more space. Then backup, reformat, restore. -- alan dot mckinnon at gmail dot com

Maxim That you run out of inodes doesn't mean that you run out of physical (or logical) space on your disk. It just means that you run out of what you could call file descriptors. There is exactly one inode per file which stores meta information about this file. Ext2-4 have a fixed amount of inodes set when you format the partition. Reiserfs and JFS create them on the fly and therefore don't have problems with running out of inodes or wasting space on unused ones. Most likely you have a bunch of very small files on our disk, for example the portage tree. These don't consume much space but a lot of inodes. My advice: Save everything to another disk and then reformat the partition with a higher amount of inodes. If you use ext2, format it with mke2fs -N 732960 /dev/sda2 This will create a file system with three times as many indoes as you had before. Hope this helps. or don't use extX.
