Hey, the following line in fstab used to work just fine for my /tmp: tmpfs /tmp tmpfs rw,size=1g,mode=1777 0 0 But since I upgraded to 8.2-PRERELEASE, /tmp will soon run out of space (usually after leaving the box overnight). % df /tmp Filesystem 1K-blocks Used Avail Capacity Mounted on tmpfs 12 12 0 100% /tmp Yes, what you see here, is not

I have a server where we use tmpfs as a cache for temporary files used by a web application. But occasionally this tmpfs thinks it is full when it isn't. [root at flask-yellow tmpfs]# touch file touch: cannot touch `file': No space left on device [root at flask-yellow tmpfs]# df -k Filesystem 1K-blocks Used Available Use% Mounted on none 393216 19296

Does someone have a working tmp on tmpfs via systemctl enable tmp.mount under CentOS8/RHEL8? This seems to work straight in EL7 ... # LANG=C systemctl enable tmp.mount The unit files have no installation config (WantedBy, RequiredBy, Also, Alias settings in the [Install] section, and DefaultInstance for template units). This means they are not meant to be enabled using systemctl. Possible

Sorry this is off-topic, but I'm scrambling to get this system in, google didn't help, and I'm sure someone on this list knows the answer cold. I'm trying to nfs-export a tmpfs disk. I saw a hint from a response about ram disks... which leads to my guess that tmpfs simply doesn't implement some method that nfsd needs. I can probably survive without tmpfs, but I'd like to

Hi all, I have some AVC in the logs and wonder how to resolve this: Under EL8 (enforcing SElinux) I have /var/lib/php/session mounted as tmpfs. # tail -1 /etc/fstab tmpfs /var/lib/php/session tmpfs defaults,noatime,mode=770,gid=apache,size=16777216,context="system_u:object_r:httpd_var_run_t:s0" 0 0 # df -a |grep php tmpfs 16384 0 16384 0%

At the risk of angering the crash Gods, my sustem has NOT crashed again since I downgraded the kernel from 2.6.18-1.2239.fc5 to 2.6.18-1.2200.fc5. Given that newfound stability, and my lack of time, I'm going to put on hold any further diagnostics, until the next kernel revision is released. I have submitted a report at bugzilla.redhat.com (bug 218128). (Ah, nuts; accidentally created a

Hello, I have a GridEngine setup with 5 subnodes and two RAIDS attached. I backed up the OS drive - 120GB - to an external hard drive - 500GB - using ddrescue. The OS drive is partitioned as: sda1 has the OS and is about 7 GB sda2 has /var and is about 4 GB sda3 has swap and is about 1 GB After backing up, there were 4KB of errors, but all at the end of the disk around 118GB. This used to be

Hi, I've seen that in the past, libvirt couldn't start VMs when the disk image was stored on a file system that doesn't support direct I/O having the 'cache=none' configuration [0]. On the KubeVirt project, we have some storage tests on a particular provider which does just that - try to create / start a VM whose disk is on tmpfs and whose definition features

Dear Sirs, I've a question belonging to the run-init utility. I'm trying to boot a full linux system from ram. Therefore I provide a kernel and initrd from a tftp server. The full rootfs is provided through a nfs-server and is at time a cpio-archive. That archive shall be copied to the local client and mounted in a tmpfs partition. After that, I want replace the oldroot bei the root

While doing some testing with converting accounts while simulating incoming mail load (no other pop/imap processes going but 4 processes converting users), we found that we were maxing out the local disk in the server with the index activity. To find out that it was the index activity, I mounted a tmpfs for dovecot to keep indexes on, and the system load dropped from 70 to 3 :) Anyway, Timo

Hi all, As suggested on the forum by Phil ( https://www.centos.org/modules/newbb/viewtopic.php?topic_id=22594&forum=37&post_id=87597#forumpost87597 ) I would like to contribute a howto on how to put /tmp on tmpfs (or shm as it used to be called). I would also like to add a bit of background information on why you would possibly want such a thing. Here are my wiki details: wiki login:

Has anyone ever mounted their /var/lib/mysql on a tmpfs or ramfs? Are there any performance gains to be made doing this? TIA

I'm using dict quota like so: quota = dict:User quota::file:/[path]/quotas/%u [path]/quotas/ is a tmpfs. The idea is to do less work on disk. Other than forcing dovecot to rebuild quotas on a reboot, are there any downsides? Thanks, Ken -- Ken Anderson Pacific Internet - http://www.pacific.net

tmpfs has a known bug of O(n^2) behavior with lseek(SEEK_HOLE); this is one situation where the noextents filter can come in handy to avoid the performance penalty of exposing accurate extents.

As part of looking into a minor issue with the group listed when using runat(1) on a UFS filesystem for Johannes (my Google Summer of Code student work on new basic file privs), I discovered an even bigger issue with UFS and extended attributes. I''ve cc''d ZFS discuss because I used ZFS as the comparison and I believe that ZFS is acting correctly but even then it might not be

Hello all, I''d like to report a tricky situation and a workaround I''ve found useful - hope this helps someone in similar situations. To cut the long story short, I could not properly mount some datasets from a readonly pool, which had a non-"legacy" mountpoint attribute value set, but the mountpoint was not available (directory absent or not empty). In this case

This is pretty much a retorical question, although I would like to know the extent of the problem and how quickly it's gonna be sorted. My problem has already been described in a previous post, i.e. clamd fails after a reboot. The cause apparently is that /run and therefore /var/run has at some point been moved onto tmpfs which means that it doesn't survive a reboot. The effect of
