Re: reading an empty directory after reboot is very slow
Vincent Lefevre vinc...@vinc17.net writes: On 2015-04-13 16:28:27 -0600, Bob Proulx wrote: Without dir_index an ext filesystem with large directories is slow due to the linear nature of directories. But with dir_index it should be using a B-tree data structure and should be much faster. So, why is it slow? I don't think dir_index has anything to do with it. An index speeds up lookups. You are not doing lookups; you are traversing the entire data structure. A B-tree data structure can take longer to traverse than a contiguous array data structure due to prefetching generally being beneficial to arrays, but less so to pointer-based structures. It's slow because every block of the directory needs to be read to get the contents, even if every block contains empty entries. You don't know that until you've read it. I also notice slowness with a large maildir directory: drwx-- 2 vlefevre vlefevre 8409088 2015-03-24 14:04:33 Mail/oldarc/cur/ In this one, the files are real (145400 files), but I have a Perl script that basically reads the headers and it takes a lot of time (several dozens of minutes) after a reboot or dropping the caches as you suggested above. With a second run of this script, it just takes 8 seconds. Your large directory is about 3.5 times the size of this one, so we would expect all things being equal that it would take 30s to read the larger directory based on the time of reading your maildir. One thing that is likely not equal is fragmentation. It is quite possible that your 30MB directory is fragmented across the disk and involves many seeks to read it all. If you really want to know if this is the case, use debugfs(8) to have a look: # debugfs /dev/sda1 # sub sda1 with your device debugfs: blocks /path/to/directory # path relative to root of filesystem That will output all the blocks used by the directory, in the order of the blocks in the directory. You'll be able to see how much seeking would be needed to read those blocks linearly. e.g. # debugfs /dev/mapper/m500-var debugfs 1.42.5 (29-Jul-2012) debugfs: blocks /lib/dpkg/info 8236 8207 8204 8221 8222 8223 8231 8232 8234 8333 8394 8395 8393 8396 8399 8400 8402 8747 8913 9258 9289 9311 9433 9405 9432 9452 9407 32084 32237 32238 32236 32245 32254 9555 9978 9908 You can see the blocks are reasonable contiguous until it jumps up to the 32000's, and then back to the 9000's. If you see a lot of that in your large empty directory, you'll find it slow to seek around the whole lot.

The only thing is, Daemontools has no way of telling it which order to

I've been using runit for some time, which is a clone of daemontools
(from the time when DJB licensing was an issue). I have a small set of
shell functions in /lib/sv/utils.sh that I source in my run scripts.
Some of these are:
temp_fail() { sleep 5; exit ${1:-1}; }
depend_on_net() {
[ -n $1 ] || return 0
ip addr show dev $1 2- | grep -qs inet.*$1 || temp_fail

depend_on_ip_addr() {
[ -n $1 ] || return 0
[ $1 = '0.0.0.0' ] return 0
ip addr show 2- | grep -qs inet $1[/ ] || temp_fail
return 0
}
depend_on_sv() {
[ -n $1 ] || return 0
sv status $1 | grep -qs ^run: || temp_fail 2
return 0
}
These allow you to put commands such as:
depend_on_sv apache
depend_on_net eth0
in the run script. If the dependency is not yet ready, it will sleep for
5 seconds and exit, leaving runsv to restart it to try again.
These will need to be adapted for daemontools, but the principle is the same.

Looks like either the packets going out the vlan is not being tagged, or something unknown is happening. I have 2 hosts directly connected to each other, both have intel i350Gb ethernet cards. host 1 physical interface eth1 = 10.0.10.68 host 2 physical interface has no ip, and vlan has assigned 10.0.10.70 I cannot see how this setup would work. Host 2 will be sending 802.11Q encapsulated packets, but host 1 will not be expecting that so it will ignore them. This would lead to the exact results you are seeing. So to counter your subject line, I would say vlan *is* tagging packets, it's just that one host is not expecting tagged packets. You will need to set up vlan 10 on host 1 and assing 10.100.110.68 to eth1.10 for it to receive packets. root@host1:~# tcpdump -vv -i eth1 -s 1500 ether proto not 0x88cc Try running that tcpdump command with -e to show link level headers.

When awk runs, it reads its input until EOF. In your loop, the first run
of awk is consuming all the input from stdin (cat input) and printing
the first line. For the subsequent iterations through the loop, awk no
longer has anything to read - it gets EOF when attempting to read the first
line. This means the script never matches anything and will not print
anything.
You will need to have awk re-read the input each time:
for (( i=1;i=3i++ )) ; do
cat input | gawk -v var=$i 'NR == var { print; exit }'
done
I've added an exit to the awk script since after the action is executed,
there is clearly no more work to be done for the rest of the file, so it
make sense to terminate early.
cat input | is not needed - it's a useless use of cat, but I don't
know if you have it here as a representation of a more complex pipeline
that is not relevant to your question. If you are literally using

gawk -v var=$1 '...' input

As others have mentioned in this thread, Honeycomb and onwards use MTP as the protocol for communicating with a USB host instead of MSC (mass storage class). I have not found a reliable MTP stack on linux, possibly because the MTP protocol itself is not very general, so treating the device as a filesystem is an abstraction mismatch. Instead, I have install an app called AirDroid on my tablet. This lets me communicate with the tablet via my browser, and supports transferring files that way.

Please post the code you have ended up with. The array method I posted
will work, but you may be using it incorrectly. From the bash man page:
If the word is double-quoted, ${name[*]} expands to a single word
with the value of each array member separated by the first character
of the IFS special variable, and ${name[@]} expands each element of
name to a separate word.
That is, the literal ${name[@]} expands to each element of the array
name as a separate word. Not one long word as you have experienced.
I've used this method plenty of times in the past, so I know it does work.

As you build up BK_LIST, you lose the ability to tell which spaces are

spaces as word separators.
To fix this, you want to make BK_LIST an array:
BK_LIST=()

I have tried fallback mode, but even in that mode I cannot configure the panels, and it does not have the GNOME 2 world clock. I like to have a single panel at the bottom of the screen with a few useful things on it. I also have two monitors so I need a panel on each, and each is configured differently. It appears that the GNOME 3 panel is completely locked down with no way to configure it, whether standard or fallback mode. I accept that for my uses, I cannot use GNOME 3, which is why I'm looking for a replacement panel for the GNOME 2 panel. I run fvwm under GNOME 2, with a configuration that has evolved over 15 years. GNOME 3 model is so far away from my current desktop model that there's no chance of giving it a go. GNOME 3 wont work with a different window manager. There's a chance I could move from fvwm to compiz, if that will work with GNOME 3, but so far, no other window manager lets me configure it in the way I currently use fvwm. I have tried xfce and kde, neither of which are to my taste. I could elaborate, but it's really just personal preference and things I just think are done poorly or incompletely. I expect I will be going back to an .xinitrc/.xsession based setup, cherry-picking the parts I like from existing tools. It looks like I will need to find replacements for: * gnome-panel: There's a number of panels, most of which would probably be ok, except that the gnome world clock is not a separate component, but part of gnome-panel. Perhaps I'll look at what can be done to split it out into it's own component that can be used on any panel. * gnome-settings-daemon: I have a love-hate relationship with this at the moment - it mostly does things well but occasionally does things contrary to what I want and refuses to budge, or just seems to flake out sometimes. Since xsettings is a fdo spec, there's hope for drop-in replacements. * nautilus: I mostly use the command line, but I like the auto-mounting, and I'm one of those few users that like the spatial mode of nautilus. * gnome-bluetooth: This gives a nice easy way to set up bluetooth devices. I hope it can be run mostly independently of GNOME. * pulseaudio: I like it, and always have. I like being to easily move audio from my little USB speakers to my internal sound card connected to my amp and good speakers, and then to my bluetooth headphones. I've been living with a hobbled Debian version of GNOME for some time, since they've ripped out pulseaudio support from gnome-settings-daemon making my keyboard volume and mute keys non-functional. * system-config-printer-applet: Oh how I hate having to manually configure CUPS, and this tool seems to work most of the time. On the plus side, it will be nice to get rid of the evolution mail client and components altogether. I tried it for a while, but could not adjust. I'm happy with a combination of mutt and gmail.

I would have thought that most people would share that goal, since building an initrd is useful for only two reasons I can think of: 1) You are building a distro kernel that needs to run on many different types of machines, since you don't know what modules would need to be built in to find the root filesystem. 2) You have a complex method of getting the root filesystem mounted - perhaps encrypted LVM on top of a network block device, etc, etc, etc. Since most people who are building their own kernels probably do not have either of these requirements, building without an initrd would make things a lot simpler. I looked into building an initrd with my kernel builds, but it just made things more complicated and I could not see the point. Is there some other reason to use an initrd when building your own customized kernels? -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe. Trouble?

These results are consistent with one of the pingtest commands returning OK (or not returning NOK, technically) I think you are looking in the wrong place. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Re: Translate user names with NFS
Dan ganc...@gmail.com writes: If you have the same user (ex. pedro) with the same name but different UID and GID NFS4 will do the conversion. Therefore I am just going to sync the names between the two machines. To do that I guess that I just need to change the file /etc/passwd and /etc/group Should I update the names somewhere else? /etc/shadow and /etc/gshadow Other specific application configs may have already recorded a username in a config/state file somewhere. You will probably also want to rename the home directory for the user and update that in /etc/passwd too. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

SSD partition alignment considerations
I'm about to do a fresh install of Debian onto a new box with a Crucial M4 128GB SSD. I want to ensure that I get the best performance I can out of the SSD so I want to make sure I take care of any partition alignment issues. I have read tytso's blog post (http://ldn.linuxfoundation.org/blog-entry/aligning-filesystems-ssd%E2%80%99s-erase-block-size) but that post is a couple of years old now and may not be relevant. Also, I cannot find any specific information on the M4's erase block size but some hints suggest it may be 512kiB, not the 128kiB used in that blog post (and the c/h/s settings no longer work for 512kiB alignment). It is necessary to worry about alignment anymore with modern SSDs? The Debian installer did not seem to have any special handling that I could see, so I suspect I would have to pre-partition the drive and tell the installer to use the existing partitions. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.
