  • Quote from tkaiser: “Quote from darkarn: “it is still better to simply schedule downtime and do things the "hard" way (i.e. manual backups and testing of such backups)? ” In my opinion yes. ” Thanks, let me see how this install goes!

  • Quote from tkaiser: “Quote from macom: “Seems it worked ” Yep, 'seems' it worked. If problems occur you realize them way too late. It's really that easy: - open files are a problem (you can't save them appropriately) - the time such a 'backup' needs is a problem (if it takes more than 0.1 seconds inconsistencies might be the result) - applications that are not aware that such a 'live backup' is about to be started have no chance to save their data/environment in a consistent state For such a 'li…

  • Thanks! Surprising that there is no hard and fast rule about backing up a live system. Maybe a middle ground is to do both to cover more variety of scenarios?

  • Quote from macom: “Quote from darkarn: “5. How much storage space do I need? ” For your OS?16GB should be enough. Depends of course on your use case. For example if you use Plex and place the database on the OS drive you might run out of space if you have a large library. But this can be avoided by placing the database on another drive. Docker container also need some considerable amount of space. Any way 16GB should be a good starting point. Quote from darkarn: “3. Set cron jobs to write logs t…

  • After some thought and playing around with my pfSense rig by using a thumbdrive on it in lieu of a HDD, I am thinking of doing the same to my OMV NAS when I upgrade from 3.x to 4.x. I am planning to: 1. Do a fresh install, install it onto a 16GB stick that I have lying around 2. Get omv-extras and then flashmemory plugin 3. Set cron jobs to write logs to a HDD (which will contain files for other functions of the NAS like VMs) 4. Get omv backup plugin to write backup of the OMV OS to the HDD too …

  • Quote from ryecoaaron: “Quote from darkarn: “VirtualBox guests are going to be development servers for my websites (and maybe NextCloud too?) ” web servers are generally low load. So, I would think you could run these on your OS disk. Quote from darkarn: “it seems that it is not a good idea in general to run OSes on USB drives ” I have a couple of servers running on USB drives. No issues here. ” Thanks, let me think about the USB drives. May go with an USB enclosure holding onto a HDD for best o…

  • Quote from ryecoaaron: “Quote from darkarn: “will there be any performance hit if my OMV boot disk is also used for VirtualBox? ” Depends on what you use OMV for and what the virtualbox guest(s) are doing. ” I am using OMV as my NAS (SnapRAID or ZFS, file server (i.e. SMB), NextCloud, VirtualBox, Plex (still deciding)) VirtualBox guests are going to be development servers for my websites (and maybe NextCloud too?) I am going to try using one HDD for OMV boot and these VMs first and then play by …

  • Quote from ryecoaaron: “Quote from darkarn: “I may not use it after all though since I realised that using the flashmemory plugin meant that logs would be in RAM until restart/shutdown; this may make diagnosis of problems harder down the road ” You could setup a scheduled job to run the folder2ram -syncall tag to write the contents in ram to files. ” Hmm sounds like a good idea but as a side question, will there be any performance hit if my OMV boot disk is also used for VirtualBox? Idea is that…

  • I tried the RAM removal idea, it works! I left only one stick of 4GB RAM and could get OMV4 to install onto the 8GB USB stick I may not use it after all though since I realised that using the flashmemory plugin meant that logs would be in RAM until restart/shutdown; this may make diagnosis of problems harder down the road

  • Quote from donh: “Not sure what hardware you are on. Old Dell and maybe some other servers had an "os install" setting in the bios. This showed the os install only 256MB of ram. Never had to use it but it drove me crazy once. Always wondered why they would do that but maybe you found out why. Anyway maybe you could remove as much ram as you can. Or do a debian minimal install and partition the diskd the way you want. Then install omv. ” I an using consumer grade Z77/Z68 boards that have no such …

  • Tested with a DVD and an USB BD drive, it worked with a SATA 1TB HDD and the aforementioned 64GB USB 3 thumbdrive (which I noticed is identified as a pSSD in Parted Magic). Same error message is seen for the 8 GB and 16 GB thumbdrives. I noticed it indeed creates a swap-file partition that is as big as the amount of RAM on the system and that on the HDD, as much as 16GB is used for OMV files alone while only 1.5 GB is used on the thumbdrive. I can't workaround for the smaller thumbdrives though;…

  • Hi I am having same issue too, tried installing on a 8GB USB 2.0 thumbdrive and 64GB USB 3.0 thumbdrive from a 8GB USB 2.0 thumbdrive or a 16GB USB 3.0 thumbdrive of various brands Sounds like either installing to a SSD/HDD or doing the Netinst method may be the only workaround. Let me see if I can get the Netinst method to work since I have to install OMV onto a thumbdrive as I have no more HDDs left Alternatively I can try the DVD method; apparently the installer USB thinks that it is a DVD ba…

  • Hi, I can confirm this works (just swapped my motherboard and NIC). This is so as within OMV (its database I think?) each HDD's identity (e.g. sda, sdb...) are tied to each HDD's serial number. Same goes for NICs if I am not wrong. As long you do not reinstall OMV (i.e. format the disk drive containing OMV), these pairings will be consistent regardless of motherboard used. You still need to run omv-firstaid and then the commands to register the new NIC (and erase all previously used NICs) if usi…

    Quote from ryecoaaron: “Quote from darkarn: “Everything passed so far, which means there are no problem? ” That is a good sign. Quote from darkarn: “Still puzzled on why this occurred in the first place ” As mentioned before, if the filesystem didn't unmount properly (process not stopping) when you rebooted, it is possible. ” Thanks, I hope this does not happen again (and if it does I at least know how to fix it.... I think?)

    Quote from ryecoaaron: “I would do the fsck. Did the short smart test show anything? ” SMART short test passed. I am running the long test now as I need to sleep As for fsck can I use PartedMagic to do it since the OS drive is mounted?

    Quote from ryecoaaron: “Quote from darkarn: “which wont matter much but why would it be there in the first place? ” It is removed but not purged. So, it isn't hurting anything.Quote from darkarn: “Did the update procedure then forget to remove it properly? ” Hard to say but it happens from time to time. Quote from darkarn: “I am also curious about the fsck in the first place that led to this. Should I schedule a disk check? ” When you rebooted, a filesystem might not have unmounted properly lead…

  • Quote from ryecoaaron: “Quote from darkarn: “Hmm I see, how big should I be worried about? 5ms maybe? ” I would worry about it when you notice it is a problem. Quote from darkarn: “I hope it wont get too much of a performance hit. ” I don't think you will notice. ” Thanks, sounds like I should just try first and report back if I see anything strange?

    Quote from ryecoaaron: “I guess you need to fix tee the same way was update-alternatives. wget http://ftp.us.debian.org/debian/pool/main/c/coreutils/coreutils_8.23-4_amd64.deb dpkg -i coreutils_8.23-4_amd64.deb Then hopefully apt-get -f install can fix things. ” Thanks! That did the trick! After those commands, I decided to run this again Source Code (1 line) It showed me the same teamviewer plugin. I went into the Plugins and saw that its Installed light is off but I can press the Uninstall but…

  • Quote from ryecoaaron: “Quote from darkarn: “Ah sorry. so if %iowait is too big, then I should be worried? ” It really shouldn't be on the OS disk. If it is too big, it would probably be higher on a usb stick since a lot of them are slower than spinning disks. ” Hmm I see, how big should I be worried about? 5ms maybe? Also based on the number of SATA ports I have, I will need the OS drive to be on the USB HDD enclosure (it will be a HDD instead of usual USB sticks). I hope it wont get too much o…
