  • Smart Errors on backup system

    tkaiser - - General

    Post

    Quote from clooner: “I am running ext4 as file system ” That's sad. With better filesystems you could run a scrub and that would tell you whether data has already been corrupted or not. But the SMART data is not bad, it's just this here what led to overall SMART status being displayed red: Source Code (1 line)This has already happened, there are no pending sectors so don't panic (especially since it's a backup disk). And with incapable filesystems it's always rather useless to look at SMART attr…

  • MDADM Error Messages

    Quote from kaufmanj1973: “an "MDADM no arrays found in config file or automatically" message. It is apparently related to a RAID system ” It's exactly the opposite. This message is telling you that there's no RAID involved AT ALL (neither exists a config nor are there RAID structures on your disks -- that's what the message is telling you). A different questions is why the message continually appears and this needs some investigation as @Sc0rp already explained.

    Wrt SMART 'issues' it's a bit hard to guess anything unless you provide SMART details. Which filesystem are you using on this disk?

  • Possible to grow linear pool?

    tkaiser - - RAID

    Post

    Quote from subzero79: “Is the same for linear, one drive goes south array dies also ” Sure, can't be any different since with classic/anachronistic RAID there's a huge gap between the device and the filesystem layer. RAID builds a block device and the filesystem sitting on top knows nothing about the stuff happening on the layers below. So all the block device layer can do is to fail completely once a device is missing/broken. It needs modern approaches that overcome those outdated concepts from…

  • How do I know the UPS is working?

    tkaiser - - General

    Post

    Quote from MrT10001: “How do I know my PowerWalker VI 650 UPS is working (monitoring and shutting down) without taking the mains power off? ” Impossible. You need to test this. Especially if you've not already collected some experiences with these things and know how 'funny' they can behave. Quote from MrT10001: “finally tested the UPS, removed mains and it kept both servers up and running. However it did not start shutting the attached OMV NAS down as it should have done.. ” That means you have…

  • OMV 3 for ODROID-XU4/HC1/HC2/MC1

    tkaiser - - Announcements

    Post

    With this latest OMV image also nand-sata-install to transfer the OMV installation over to a HDD or SSD is finally working. But you should keep in mind that this will prevent disk sleep with HDDs (please check also the JMS578 spindown firmware issue that is about to be resolved soon). And you must keep in mind that you need to create partitions on a connected disk first otherwise OMV won't allow you to use this disk also for data later! So a good recommendation could be to use 2 partitions: 10GB…

  • OMV 3 for ODROID-XU4/HC1/HC2/MC1

    tkaiser - - Announcements

    @ryecoaaron: Sorry to bother you again with an image update: OMV_3_0_92_Odroidxu4_4.9.61.img.xz (MD5 hash: e349f2fa1acebdeede8210b0ff7e9959) Please replace this on Sourceforge since Hardkernel will pretty soon sell a new eMMC type (that is finally useable on all their various ODROIDs -- no more color coding hassles any more!) and as they write: "Please consider releasing new images since some users can’t update safely because of the instability just in case. In the first boot process(or any time…

    Quote from elastic: “I have mixed feelings about the whole scrubbing feature ” ...but want to use RAID (where OMV also scrubs regularly unless users decide to behave irresponsible)? It feels really strange hearing of people wanting to waste 2 entire disks for something they try to sabotage at the same time (added complexity requires continous testing. Most of these 'My array has gone! Where is all my data' threads every other day here are related to users blindly trusting in technology instead o…

  • Raid 10 boot - how to?

    tkaiser - - RAID

    Post

    Quote from Sc0rp: “RAID1 as boot-device brings only more reliability if different drives of the same technology are used (e.g. one HDD from Seagate and one from WD - of course with the same base specs), on SSDs i didn't recommend that ” With RAID-1 and SSDs not following this rule and using exactly the same devices (especially when even firmware revision is the same) is really dangerous since SSDs die for other reasons than spinning rust (eg. firmware failures, we had this with almost all vendor…

  • Quote from mcdoug8: “DId I skip a step in expanding the image? ” No, you skipped reading the readme.txt at the download location explaining what's needed to make use of the 3rd partition if you want to use the remaining capacity (the older OMV image used 4GB for the rootfs while latest images uses now 8GB -- these are of course 'manufacturer units' and real sizes are 3.6GB and 7.3GB)

  • Quote from flmaxey: “(Provided for searches) ” For the same reason I would suggest checking with 'ip addr' first whether this is not just a cosmetical/timing issue (on almost all OMV ARM images I built within the last months it's exactly like this: when using serial console OMV greets with 'no network interface found' while half a second later dhcpclient got an address and everything is fine)

  • The latest image for C2 contains one bug that striked in environments with IPv6 enabled/propagated via DHCP: forum.armbian.com/topic/3953-p…findComment&comment=42780 Please check this first and also whether things change if you eliminate all interface details from OMV's config.xml and also eliminate eth0 in /etc/network/interfaces, then reboot (DHCP will work since network manager now takes over) and then change/add in OMV UI eth0 again.

  • Just as a referene the summary what makes these OMV SBC images generated with Armbian's build system somewhat special: forum.armbian.com/topic/3953-p…findComment&comment=44097 Edit: almost forgot to mention: All of ayufan's OMV images for ROCK64 also contain those relevant performance stuff (we added that a while ago already) so it's fine to choose his OMV images too

    Quote from matteu: “What is my problem ? ” Well, hour hard disk most probably? Please keep in mind that HDD all get slower the more they're used (capacity wise): forum.armbian.com/topic/1925-s…findComment&comment=15319 And test locally storage performance on OMV with eg. iozone (apt install iozone3)

  • Quote from Muffkins90: “i am almost 100% sure they they configured for 1GB speed ” What about verifying this first? Grab iperf and jperf.exe and test at the network layer. If you're staying below 100Mbits/sec you know where to search for next. For local storage tests I would recommend iozone ('apt install iozone3') and for combined tests I would recommend Helios' LanTest (since eliminating the client side storage bottleneck often involved). BTW: older 2.5" 5400 rpm SATA drives that are not entir…

  • Quote from lsdfr: “the one last question, whats the /etc/cron.daily/log2ram: actually do ? ” Nothing, it's a bug on the older images. Please delete the file and use the search field in the upper right corner for 'folder2ram' (since this is active in OMV instead of Armbian's log2ram)

  • Quote from lsdfr: “First is 4GB in size the other 11GB and 310mb at the end free. ” Ah, then you're using an older image and the fs resize happened already. If it's really just 2 partitions then they should be both ext4 (we switched to btrfs later but this needs then a 3rd ext4 partition at the beginning to boot since Hardkernel's u-boot can't cope with btrfs directly). Untested but should work: delete the 2nd partition since it seems to be unused anyway and then just Source Code (2 lines)SD car…

  • Quote from fmomv: “I'm now somewhat familiar with RPi, so i like to continue using it, because I'm not the hardcore-kernel-recompiling linux-expert. ” Hehe, yeah. There's always an absurd excuse to justify using the worst possible platform possible. None of the other way more performant and suitable ARM platforms for OMV requires knowing what a kernel or even Linux is.

    Quote from tranz: “Then read some post regarding raid5/6 not very good option with btrfs file system ” You should start to read more carefully (or better articles). While btrfs contains own RAID5/6 implementations that are known to cause troubles in situations the usual 'I play RAID at home because I don't understand the difference between availability and data protection' dude never will run into there's nothing wrong using btrfs on top of an existing mdraid6 other than using RAID-6 if you coul…

    The redundant RAID modes are only about availability ('business continuity'), backup provides data protection. It's as simple as this.
