The invaluable advantage of having a larger external hard drive is that capture can continue for a loooong time even if there are internet problems or processing problems, and then once connectivity is re-established, the Red Hen automatic scripts can do their job, or an actual person can access the station remotely and fix the problem, and then the Red Hen automatic scripts can finish the job.<em><strong> In the special case where data transfer via internet cannot be arranged<\/strong><\/em>, include a powered USB hub and connect external hard drives to it; in this way, mere USB-powered portable 1TB drives can be used; and these portable drives can be mailed or carried by some wandering Red Hen courier to a place where the data can be absorbed.

We will complete the configuration with your help, ensuring that the Raspberry Pi can talk to the HDHR3 and start recording. Here are some of the steps:<\/p>\n<ul class=\"n8H08c UVNKR\">\n<li style=\"list-style-type: none;\">\n<ul class=\"n8H08c UVNKR\">\n<li id=\"h.p_ID_385\" class=\"TYR86d zfr3Q\">Run find-tuners.sh and edit \/tvspare\/tuners\/signal<\/li>\n<li id=\"h.p_ID_387\" class=\"TYR86d zfr3Q\">Get the PID on the interesting channels, as described here, and add them to \/tvspare\/tuners\/lineup<\/li>\n<li id=\"h.p_ID_389\" class=\"TYR86d zfr3Q\">Add the local tv program grabber definition to the script \/usr\/local\/bin\/xmltv-download<\/li>\n<li id=\"h.p_ID_391\" class=\"TYR86d zfr3Q\">Run the scheduler script \/usr\/local\/bin\/schedule on the chosen programs and update crontab<\/li>\n<li id=\"h.p_ID_393\" class=\"TYR86d zfr3Q\">Add the new machine to the list of Red Hen capture stations at our HPC processing pipelines at UCLA and CWRU<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<div class=\"CjVfdc\">\n<div class=\"PPhIP rviiZ\">Under the hood<\/div>\n<\/div>\n<h2 class=\"CjVfdc\"><span style=\"color: #800000;\">Transferring data<\/span><\/h2>\n<p id=\"h.p_ID_401\" class=\"CDt4Ke zfr3Q\">Where the internet connection is fast enough, Red Hen transfers data directly and no further action is needed. If the connection is too slow to handle the transfer of uncompressed files, the best solution is to add a local server to handle the compression task; compressed files are typically around 5% of the size of uncompressed files, and therefore transfer much more easily.<\/p>\n<p id=\"h.p_ID_403\" class=\"CDt4Ke zfr3Q\">If neither a fast internet connection nor a server to handle local compression is available, the fallback is to fill up a drive and swap it out for manual transport.<\/p>\n<p id=\"h.p_ID_405\" class=\"CDt4Ke zfr3Q\">Add the new drive by plugging it into power and into a spare USB port on the RPi. Check dmesg for the logical device it attaches to &#8212; typically \/dev\/sdb, but it could switch places with the existing drive. Use gdisk to partition it into one linux partition. First press x and then z to remove previous partitions, then start gdisk again and add a new partition by pressing n and then w to write. Next, add the file system and label it:<\/p>\n<ul class=\"n8H08c UVNKR\">\n<li style=\"list-style-type: none;\">\n<ul class=\"n8H08c UVNKR\">\n<li id=\"h.p_ID_407\" class=\"TYR86d zfr3Q\">mkfs.xfs \/dev\/sdb1<\/li>\n<li id=\"h.p_ID_409\" class=\"TYR86d zfr3Q\">xfs_admin -L HD2 \/dev\/sdb1<\/li>\n<li id=\"h.p_ID_411\" class=\"TYR86d zfr3Q\">add it to \/etc\/fstab, copying the HD1 line and changing to HD2<\/li>\n<li id=\"h.p_ID_413\" class=\"TYR86d zfr3Q\">mount \/mnt\/HD2<\/li>\n<li id=\"h.p_ID_415\" class=\"TYR86d zfr3Q\">chown csa:csa \/mnt\/HD2 (as root)<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p id=\"h.p_ID_417\" class=\"CDt4Ke zfr3Q\">We can either copy the recorded files to the new drive or switch recording to the new drive. It&#8217;s generally a bad idea to move video files from one drive to another unless you really have to; the files are so large that they place extra strain on the drives that can break them. However, sometimes this is still the best option, and we can use a command like this (can be given as a one-liner):<\/p>\n<div class=\"s1gOZb\">\n<pre id=\"h.p_ID_419\" class=\"CDt4Ke zfr3Q FVr0A\"><code>day 2017-02-02<\/code><\/pre>\n<\/div>\n<p id=\"h.p_ID_421\" class=\"CDt4Ke zfr3Q\"><code class=\" qM9fHf\">for d in {478..0} ; do D=<\/code>\/mnt\/HD2`pwd` ; mkdir -p $D<\/p>\n<div class=\"s1gOZb\">\n<pre id=\"h.p_ID_423\" class=\"CDt4Ke zfr3Q FVr0A\"><code> if [ ! -d $D ] ; then break ; fi<\/code><\/pre>\n<pre id=\"h.p_ID_425\" class=\"CDt4Ke zfr3Q FVr0A\"><code> for f in *mpg ; do rsync ${f%.*}.{mpg,txt,len} $D -av ; sleep 10 ; echo . ; done<\/code><\/pre>\n<pre id=\"h.p_ID_427\" class=\"CDt4Ke zfr3Q FVr0A\"><code> sleep 60 ; echo .. ; day + 1<\/code><\/pre>\n<pre id=\"h.p_ID_429\" class=\"CDt4Ke zfr3Q FVr0A\"><code>done<\/code><\/pre>\n<\/div>\n<p id=\"h.p_ID_431\" class=\"CDt4Ke zfr3Q\">&#8212; where 2017-02-02 is the first day to copy, moving forward a day at a time to the present, 478 is the number of consecutive days to copy, and HD2 is the name of the drive we&#8217;re transferring the data to. The job pauses ten seconds between video files and a minute between days to lower the strain on the drive. When the copy job is done, unmount and unplug the transfer drive.<\/p>\n<p id=\"h.p_ID_433\" class=\"CDt4Ke zfr3Q\">If instead we replace the old drive with the new, we first need to create the directories we need, as user csa:<\/p>\n<ul class=\"n8H08c UVNKR\">\n<li style=\"list-style-type: none;\">\n<ul class=\"n8H08c UVNKR\">\n<li id=\"h.p_ID_435\" class=\"TYR86d zfr3Q\">mkdir -p \/mnt\/HD2\/tv \/mnt\/HD2\/ts \/mnt\/HD2\/xmltv \/mnt\/HD2\/software \/mnt\/HD2\/system\/log \/mnt\/HD2\/system\/logs<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p id=\"h.p_ID_437\" class=\"CDt4Ke zfr3Q\">We then need to change these symlinks &#8212; first done by user root, but then chown to csa:csa:<\/p>\n<ul class=\"n8H08c UVNKR\">\n<li style=\"list-style-type: none;\">\n<ul class=\"n8H08c UVNKR\">\n<li id=\"h.p_ID_439\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/tv \/tv (root directory)<\/li>\n<li id=\"h.p_ID_441\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/spool \/mnt\/spool<\/li>\n<li id=\"h.p_ID_443\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/software \/root\/software<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p id=\"h.p_ID_445\" class=\"CDt4Ke zfr3Q\">These links should be created by user csa:<\/p>\n<ul class=\"n8H08c UVNKR\">\n<li style=\"list-style-type: none;\">\n<ul class=\"n8H08c UVNKR\">\n<li id=\"h.p_ID_447\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/tv \/home\/csa\/tv<\/li>\n<li id=\"h.p_ID_449\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/ts \/home\/csa\/ts<\/li>\n<li id=\"h.p_ID_451\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/system \/home\/csa\/system<\/li>\n<li id=\"h.p_ID_453\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/xmltv \/home\/csa\/xmltv<\/li>\n<li id=\"h.p_ID_455\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/xmltv \/nest\/xmltv<\/li>\n<li id=\"h.p_ID_457\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/system\/log \/nest\/log<\/li>\n<li id=\"h.p_ID_459\" class=\"TYR86d zfr3Q\">ln -sf \/mnt\/HD2\/system\/logs \/nest\/tuners\/logs<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p id=\"h.p_ID_461\" class=\"CDt4Ke zfr3Q\">Once everything is switched over, the Red Hen software will record to the new drive. Unmount \/mnt\/HD1 and unplug it, and transport it to a location with a faster internet connection so that the data can be transferred.<\/p>\n<p id=\"h.p_ID_463\" class=\"CDt4Ke zfr3Q\">If we need to read the XFS-formatted transfer drive on OS X, use fuse-xfs &#8212; it&#8217;s read-only and slow, but it works.<\/p>\n<p id=\"h.p_ID_465\" class=\"CDt4Ke zfr3Q\">To check that the capture drive remains available, we use this spell on root&#8217;s crontab:<\/p>\n<p id=\"h.p_ID_467\" class=\"CDt4Ke zfr3Q\"># Attempt to remount the hard drive if it&#8217;s failed<\/p>\n<p id=\"h.p_ID_469\" class=\"CDt4Ke zfr3Q\">59 * * * * if [ !
