  • This is how I install OMV on any random Debian out there: Source Code (2 lines)Menu driven installation checking Debian version and then either installing OMV 3 or 4 (since it's insane to run OMV 2.x based on Debian Wheezy in 2017). Look like this then: OMV 4 image for Raspberrypi

    Quote from bookie56: “however, have been reading a lot of horror stories about resyncing after replacing a damaged drive.... ” So you neither got @ness1602 part about 'backup' nor 'Raid0' (there 'resync' isn't an issue at all). I've the strong feeling your data will remain at high risk regardless what you do BTW: Not 'horror stories' are important but you understanding the chosen technological approach and then either implementing it correctly or avoid it. 'Implementing correctly' means testing …

    Quote from bookie56: “A good hardware raid is ” ...called 'a single point of failure' -- you need at least two of these RAID controllers to be safe, you need to test all scenarios that are possible (you don't know what that is if you're not storage professional with a few years of experience). Nobody does this since the only reason why most people think about RAID is a good feeling since 'something with redudancy'.

    Quote from weebnuts: “Hardware Raid5 is much better ” 'Better'? No. It's just a different attempt to loose all your data if you don't care about backup (which a lot of OMV users do for reasons unknown to me). BTW: RAID5 was suitable for some use cases back in last century. Today it's used mostly for psychological reasons (providing a good feeling since 'something done for $redundancy' without spending much thoughts on anything)

  • Which RAID or HBA card

    Quote from rabudde: “Yes, I meant it's a link aggregation, i.e. LACP, with 2GBit/s. Why would then a single link be the bottleneck? ” Since LACP/bonding/trunking works this way. It's not a magic bandwidth increase but just a link distribution / failover algorithm. We should never talk about '2GBit/s' when using a bond with 2 links since it's really just 2 x 1 GBit/sec. Same when you use 3 or 5 links, then it's just 3 x 1 GBit/sec or 5 x 1 GBit/sec. A true 5GbE connection is something completely …

    Quote from Sc0rp: “awwww, come on, @tkaiser ... it is a bond of two 1GbE-interfaces - what else? ” If it's a bond (link aggregation) then why being concerned about getting 170/200 MB/s at the storage layer if the network is bottlenecked by single link Gigabit Ethernet speed anyway? If we would talk about something else than bonding (eg. SMB Multichannel or SAN stuff like multipathing) I would understand talking about a '2GB LAN interface' but link aggregation / bonding does NOT work this way

    Quote from rabudde: “I can copy data inside RAID volume with round about 170-200MB/s so I can satisfy my 2GB LAN interface ” What is a 2GB LAN interface? I know 1GbE and next 2.5GbE but nothing in between (already asked that back then but you chose to ignore. Why?)

    Quote from raffie77: “Ill install homebrew end ddrescue ” It's a matter of minutes, ddrescue will tell you if there is any reading trouble and performance is also great. The card reader in my MacBook writes/reads with up to 80MB/s and ddrescue on average reads with ~40MB/s (though different story since the card reader is passed through to a Linux virtual machine that checks the OS images directly after)

    Quote from Wrenchit2: ““ZFS”This solution requires 8GB ECC ram ” No. Doesn't become more true if repeated over and over again. While it's a reasonable recommendation neither the 8GB nor the ECC DRAM is a hard requirement for ZFS. It would be really nice if people could stop copy&pasting wrong information from the past over and over again.

I run with a more recent version since I tested out Anand Moon's patch to improve USB3 stability: forum.odroid.com/viewtopic.php…&t=27548&start=50#p201153 Igor (Armbian core dev and maintaining the apt rep…

And I won't waste time on trying out since using these images headless is the best idea anyway.

Bash and not Python since I realized a decade ago that I should only do prototyping/scripting instead of real coding since in every customer project so far the coders asked two or at least one question that I would've never thought about since already 'too much into'. One absurd side effect: If you need someone experienced with both AppleScript and Unix…
