similar to: MySQL on tmpfs?

Hello, I was using a bunch of cpios in initramfs as a working system, and wondering why the unused files weren't being paged out to swap. So I reread ramfs-rootfs-initramfs.txt and now I know. So I wrote the attached utility. It creates a tmpfs, moves all files on the initramfs, moves / and executes the real init. It works, even with hardlinks, but it isn't the correct approach. Have

I have bind running on two servers. Both servers are running bind-9.2.4-7. When I update a zone file on the primary and reload bind, the secondary receives a notify, but does not initiate an AXFR. The only way I can get the secondary to update is to delete the zone file on the secondary and restart named. Any ideas what might be wrong? Mike

"to memory" means: mounting a ~2 GByte filesystem [ tmpfs?, or ramfs? ], and put the "/tmp" on it. [ e.g.: 4 GByte ram in the pc ]. what to write in the "/etc/fstab"? I would like to collect the [ answers too:P ]: Advantages: - Memory is way faster then HDD/SSD, so it could speed things up - "SSD amortization" is less Disadvantages: - Security?

I am about to lease another server to be a backup web/mail server with a replicated mysql database. The current live server is a dual Xeon 2.8Ghz. Would I do better to get another Xeon server or an Opteron based server? My concerns are compatibility of the database and the SSL certificate currently running on the Xeon machine. Are these concerns unfounded? TIA Mike

dovecot-1.2.7 If /var/run/dovecot does not exist when dovecot starts up (e.g. required when /var/run is a tmpfs/ramfs), it creates it. But it creates it with the wrong file mode -- the directory is mode 777. Being world writable means any user could change the name of any file within the directory, including the login directory, and then create their own new login directory. Or remove the pid

Hi, I am a newbie into kernel booting process. I have read few things about boot process of the linux kernel. I am stuck at few things, which I am confident, someone from the list might help on - - If I pass a ramfs image as an intrd paramter from the bootloader (say grub), then will the kernel treat this as a ramfs image only? - initrd image is also, packed using cpio archive, then

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.

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

I've set up a 1GB tmpfs filesystem on a system with a single IDE disk and 2GB's of memory. I'm storing a large amount of RRD files (~300MB) on the tmpfs filesystem to make their generation a bit speedier... this part works great. However, I want to rsync these files over from time to time to a directory on the local filesystem (same physical server). I'm using rsync 2.6.4pre3

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%

I have been trying very hard to seek help with my very complex issue but so far none have been successful. So I would like to try this mailing list, maybe there are some experts who know what they're talking about. Please refer to my experts-exchange question, all the required information will be there. It is more practical to send you to the webpage than paste out what I've done.

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:
