Tmpfs issues

Hey, every app I try to install with packer, aurget or yaourt fails due to 'No space left on device'
It's a fresh install of Arch but I've noticed this:
tmpfs                                                   493M  493M     0 100% /tmp
this of course empties with a reboot.
here is my hard drive breakdown:
$ df -h
Filesystem                                              Size  Used Avail Use% Mounted on
udev                                                     10M     0   10M   0% /dev

/dev/sda1                                               198M   17M  171M   9% /boot
I've never had this issue before.
also get this message trying to install the rt kernels:
bsdtar: Error exit delayed from previous errors.
yet it works on my other pc... both new installs..

Forgive me if I've missed the answer in any of the several threads on this topic, on the arch-dev-public mailing list and in the linux-docs information on tmpfs, but I haven't figured out what the reason is for recommending mounting /tmp as tmpfs instead of as a hard drive mount. It sounds like from the discussions on the forum that several people (R00KIE being one) recommend leaving /tmp mounted on the hard drive. I understand the mechanics of the change (and have implemented it with no ill effects on all my Arch machines), just not the reasoning behind it.
For a "typical" older machine with 1-2GB RAM and "typical" internet/email/office usage it sounds like tmpfs would be fine. What other 'gotchas' should we look for that might lead us to leave /tmp assigned to our hard drives instead?
Thanks!

  • Special device does not exist, FSTAB Issue

    I set up this arch64 install last night, and till now I've managed all right except for one niggling issue.  For some odd reason, when I installed everything I forgot to add my "sandbox" partition in Fstab.  I thought I could just generate a UUID then add a line to Fstab later, and I did just that.  However, as its not part of my LVM, I'm wondering if thats why I cannot mount my sandbox partition from Fstab.  Ideas appreciated.

    NFS was the only one file type recognized by the discovery process...I am quite new to virtualization, actually spent last whole week trying and fixing one or other issue with the VM server :D
    If you know how I could avoid NFS in the entire scenario (as this is just for learning purpose) I would be grateful :)

  • Hibernation issue

    I have a problem with hibernate script. This is what happens:
    1. I run dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Hibernate
    2. System hibernates nicely and quickly.
    3. I power the computer back on
    4. System resumes nicely (%s goes really fast)
    5. Instead of desktop, I see black screen with blinking "_" sign in the top left corner.
    At this point I have to hard-reset the computer.

    You mean the arch wiki article that's flagged as poorly written?
    FWIW I've always used pm-utils, also the Arch Wiki way, and I've had few issues. Basically, you just add the resume path to /boot/grub/menu.lst and then run:
    # pm-hibernate

  • [SOLVED] File name encoding issue

    Hi all,
    I have a large series of files with accented characters, they were all displayed nicely, but at some point, when I copied them to another computer, the characters were replaced by codes, for instance: "ó" --> "ó".
    +Renaming ie. "Pasó" (bad encoding of "Pasó") --> Pasó, while writing it, it shows the correct character, but when pressing enter the name remains ("Pasó")
    +If I rename the file to something else and then to the correct name, it will accept it: Pasó --> Pas --> Pasó will display correctly.
    I don't know if it's a system wide encoding issue because new files are displayed correctly, but I would like to know if I have to change file names manually to make them right.
    PS. When copying bad encoded files to another FS (like a USB drive), nautilus and bash refuse to copy them.

  • Cache-flush VM-related performance issue

    Dear forum,
    I've got a peculiar performance issue going on with the BDB pagecache being flushed to disk. I've managed to reproduce the issue perfectly on three out of three quite different systems that I've tried on, so it is at least quite well-defined.
    My usage pattern for the database in question is such that I periodically (perhaps once every 10-60 seconds or so) need to read through an amount of values (around 500-2000 or so) from a database containing a rather large amount (in the millions, at least) of keys. There are a few writes for every such batch, but not very many (a couple of tens). The keys that are read each batch are quite random, and very likely to be completely different from batch to batch. The database is a DB_HASH.
    When I do that, BDB seems to dirty a lot of pages in the page cache (which I have currently sized at 512 MB so that pages don't have to be forced out from it), from what I can tell by manipulating refcounts and stuff, so all in all, a single batch seems to dirty some 10-40 MB or so of the mmapped cache region. (I check this using pmap -x on Linux.) Note that when I speak of pages and the dirtying of them here, I mean at the VM level, not the BDB level.
    A while after this has happened, the VM comes around and wants to flush the dirty pages to disk, so it batches writes of large portions (often the entire set of dirty pages, but sometimes it only does 10-20 MB or so at a time; this detail shouldn't matter) of the dirtied pages to the backing block device. Since the dirty pages are often rather interspersed in the region file, such a flush usually requires a couple of thousands of write ops, so it might sometimes take up to 10-20 seconds for the requests to complete.
    If the program, then, again tries to dirty any of the pages while they are waiting to be flushed, which is often the case, the VM will block it until the page in question is flushed. This means that the thread in question might very well be blocked for up to 20 seconds, causing quite annoying wait times.
    How to deal with this problem? I've considered trying to put the region files on tmpfs or so, but that seems like such an excessive measure for a problem which, from what I can tell, should be commonplace.
    On a very related note, I've noticed a large discrepancy in the I/O performance between the systems I've tried this on. Two of the systems in question manage to carry out some 200-500 write ops per second on my test load, while the third manages closer to 2000-3000 write ops per second, which makes quite a difference. What makes it very weird is that the faster system uses the exact same hard drive as one of the slower systems. I know this isn't exactly a BDB-specific question, but I thought someone around here might have experience in the matter. All three systems use Linux and S-ATA hard disks (not SSDs), but they use different S-ATA host adapters, different kernel versions and are configured in quite different ways.
    Thanks for reading my wall of text! I'm sorry for dragging on so long, but I didn't know how to describe the situation more briefly.
    Edited by: Dolda2000 on Mar 23, 2013 8:08 AM

    As a follow-up on this, it appears that the blocking behavior was introduced in Linux 3.0 to stabilize pages under writeback:
    http://lwn.net/Articles/486311/
    It seems that the commits that introduced the behavior can be safely patched away, and also that it is due to change in 3.9, but for now, this is not the route I took to solve it.
    Rather, I wrote a patch to Berkeley DB to allow me to store the region files in another directory than the environment root directory, and used it to store them in /dev/shm -- that is, on tmpfs, which avoids writeback of the region files altogether.
    If you want the patch, it is here for db4.8 (which what Debian Stable uses), and here for 5.1, which is what Debian Testing uses.
    (For some reason, the hyperlink format suggested by the forum doesn't seem to be working?)

    please help
    ta

    yeah someone else set this up and i'm trying to help, but not getting very far. I can see the lun on the storage is there, not sure how to check if ovs tried to access it. I thought issue_lip or scan should have picked up the extra lun, is that wrong?

  • Linux Partitions  - tmpfs

    We have installed oracle linux 5.x using the custom partitioning and the OS installation was successfully completed and we were able to access the Linux OS without any issues.
    But, while observing the /etc/fstab file, it has an additional partition entry which we have not created during the custom partition.
    Why this below partition was created and purpose:
    tmpfs /dev/shm tmpfs defaults 0 0
    # cat /etc/fstab
    /dev/VolGroup00/LogVol00 / ext3 defaults 1 1
    LABEL=/u01 /u01 ext3 defaults 1 2
    LABEL=/usr /usr ext3 defaults 1 2
    LABEL=/var /var ext3 defaults 1 2
    LABEL=/tmp /tmp ext3 defaults 1 2
    LABEL=/swap /swap ext3 defaults 1 2
    LABEL=/boot /boot ext3 defaults 1 2
    tmpfs /dev/shm tmpfs defaults 0 0
    devpts /dev/pts devpts gid=5,mode=620 0 0
    sysfs /sys sysfs defaults 0 0
    proc /proc proc defaults 0 0
    /dev/VolGroup00/LogVol01 swap swap defaults 0 0
    [root@nfs-stg-db1 ~]#
    Becuse of this OS additional partition the Oracale Database Alert Log file reporting ORA-07445 errors.
    Please advise.

    Thanks for your respose..
    But we have commented this line in /etc/fstab file and re-booted the machine. Then restared the oracle database and the application without any issues and we are not receiving the ORA-07445 errors in database alert log file. Please check the oracle metalink note ID 1191471.1
    #tmpfs /dev/shm tmpfs defaults 0 0
    and now applicaiton is working fine without any issues.
    Cause
    You have set additional mount options on the shared memory device, /dev/shm, other than just the option named defaults.
    Solution
    If you see any other mount options in file /etc/fstab after the word "defaults" for /dev/shm,
    such as nosuid, nodev, or noexec:
    none /dev/shm tmpfs defaults,nosuid,nodev,noexec 0 0
    then remove these options from the entry in /etc/fstab:
    none /dev/shm tmpfs defaults 0 0
    shut down the database instance, and reboot the system. Restart the database instance. The errors should no longer appear.
    After executing the above action plan the issue has been resolved.
    But our concern is, what this partition and why its created automaticall? if this partition is created automatically, it should also handle the oracle database.
    Appreciate your advice.

  • [SOLVED] SystemD NTFS partition issue's

    Hey archers,
    hope someone here can help me
    recently began testing systemd & I am facing a problem where I have to ctrl+d or give root password during every boot up due to systemd having problems with my ntfs partition ( i mount at boot as I have symlinks to that partition for documents & programs which run in wine)
    I have not enabled anything to do with mounting or even added the fuse module to load as it has already picked that up!

    as you can see my partitions are being mounted TWICE which is not what I want or expected!
    is there more documentation on what systemd does with mounts that could explain why i have multiple mount points for partitions or is this due to systemd discovering my partitions & mounting them at points based on label names & then parsing my FSTAB as well!
    I have read the wikki but there is very small info there & the links have not provided an explanation for this unwanted behaviour

    OK,
    After being spurred on to try to do this thing properly, this is what I came up with today.
    My fstab line (for a USB NTFS disk):
    /dev/sdb1 /media/samsung ntfs-3g noauto,users,rw,nodev 0 0
    Then I created the /media/samsung folder and gave the audio group read/write permissions.
    It seems that non-root users can only mount an ntfs partition if they use a version of ntfs-3g with fuse included, so I replaced ntfs-3g with the version from AUR, having removed from the PKGBUILD file the option "-with-fuse=external" (see this thread: http://bbs.archlinux.org/viewtopic.php?id=44844 ).   I also had to set
    the ntfs-3g binary to setuid-root, dealt with here: http://www.tuxera.com/community/ntfs-3g … privileged (note- the instructions say this is discouraged, but it seems using ntfs partitions in linux requires some compromises).
    I can now mount the drive as an ordinary user.
    Then I set mpd back to run as user mpd, checked the audio group had access to all the mpd folders, and all was well.
    One hiccup which you might not have: mpd was unable to access my (external) sound card at first.  To solve this one, I used
    chmod 770 /dev/snd -R && chgrp audio /dev/snd -R
    As far as I can remember, that's everything.

  • Tmpfs free space versus the "free" command

    I've always thought this possible, so today I tried it:
    I have 2 gigs of physical RAM, and no swap partitions, so my memory limit is a hard 2 gigs.
    I made 2 1-gig tmpfs mounts; nothing complained.
    I filled them up one at a time, and kept checking both free memory (with free) and free space on the tmpfs mounts -- as I started to get near the limit of my system's RAM, free still showed plenty of RAM free in the +/- row.
    Neither free nor df gave me any indication that the system was dangerously low on memory. (I assume from a bit of Googling  that "free" considers the size of tmpfs's to be part of the "cached" column, as nothing else was big enough to contain them.)
    Anyhow, I added a few more files to the tmpfs and the system locked up for a while... After about 3 minutes of hard drive thrashing (which was a bit distressing, but since my files look OK I guess it was desperately running sync again and again to try to free RAM for the tmpfs), a couple programs died and everything went back to normal.
    So, in an effort to have that not happen again (since I use tmpfs heavily; it's a nice way to screw around with big files without waiting on hard drives), I wrote this little shell script:
    #!/bin/bash
    #prints worst-case free memory, from /proc/meminfo
    total=`grep MemTotal /proc/meminfo | gawk '{print $2}'`
    used=`grep Committed_AS /proc/meminfo | gawk '{print $2}'`
    echo "Free RAM in the worst case: " $(($total - $used)) "kB"
    and put this in my .bashrc:
    alias free='free; wcfree'
    alias df='df; wcfree'
    ~Felix.
    PS: If it's not possible to make stuff crash with only a single tmpfs, please let me know -- that would be good knowledge, and make me feel silly for writing this :P

    The advice I got was to shrink the database and reexpand it. And reindex all tables because of defragmentation.
    I don't know if it works, and I would be hesitant to try it, because I believe there is an issue with DBCC SHRINKFILE being awfully slow when there is LOB data.
    I like to believe that your odds would be better if you used varbinary(MAX), and given how easier varbinary(MAX) is to work with your life would be happier two. But I don't know how that would work with your merge-replication scheme. And if you use READ/WRITE/UPDATETEXT
    you need to change that code.
    You say you cannot create a new table and copy data over because of merge replication. Would it be possible to create a new column, copy data over, drop the old column and rename? I have no experience with merge replication myself, so I don't know of
    the repercussions. If you do this, you need to run DBCC CLEANTABLE to get rid of the space.
    For that matter you could try DBCC CLEANTABLE in the state you have now. Not that it should help from you have told me, but you never know...

  • Bootchart2-git: bootchart-renderer fails to mount /lib/bootchart/tmpfs

    I recently bought a new laptop and made a fresh Arch installation. After a few initial annoyances I got everything working more or less as intended, except bootchart. Since the wiki said "Note: An alternative to Bootchart is bootchart2, which at least has more recent activity than 2005. It can be found on the AUR as bootchart2-git. It uses python for generating the final chart instead of a JVM. ", I used the git version from AUR, if that matters.
    [r-a@vinter ~]$ /sbin/bootchartd start; sleep 1; /sbin/bootchartd stop
    10834 109
    bootchart-collector tmpfs mount to /lib/bootchart/tmpfs failed
    Can't extract boot chart from collector
    [r-a@vinter ~]$
    A peek at the source code(collector/collector.c:625-630):
    if (mount ("none", TMPFS_PATH, "tmpfs", MS_NOEXEC|MS_NOSUID, NULL) < 0) {
    if (errno != EBUSY) {
    fprintf (stderr, "bootchart-collector tmpfs mount to " TMPFS_PATH " failed\n");
    return 1;
    strace output:
    15146 mount("none", "/lib/bootchart/tmpfs", "tmpfs", MS_NOSUID|MS_NOEXEC, NULL) = -1 EPERM (Operation not permitted)
    man 2 mount says this:
    EPERM  The caller does not have the required privileges.
    I haven't tried changing the default path to mount to for example something like /tmp/, perhaps it'd solve the privilege issue... What bugs me is that the default config indeed uses /lib/bootchart/ as it's base path... So I can only assume that it somehow should have permission to mount tmpfs to that directory? Whatever, I am a bit clueless here. What next?

    Setting the SUID bit of bootchart-collector with chmod +s didn't do the trick; though I am not entirely sure if it was because of failed mount - I can't check it right now.
    ...anyone...?
