All the files I'll have in the pool I have local or offsite backups of, I just don't want to serve out corrupt files, or miss the signs that I need to take action. The goal is to know when/if a drive or the pool is having any integrity errors since I have this odd fear that if a file is corrupted, it gets mirrored and that's it. So far I've been using zpool status and zdb and trying to grok their man pages but as I do that I'm wondering if there are other tools and commands I've missed in looking. I've been looking for how I can monitor the health of this pool, preferrably over SSH/CLI but I tend to keep finding web/GUI recommendations and systems like Proxmox, and I'm sure they're great, and something for my future, but right now I'm trying to understand some ZFS nuts and bolts on the command line. I'm new to ZFS, having previously used simple drive and LVM setups with rsynch for psudo-mirroring before on Linux. The -f is there are the disks are dissimilar sizes, so I get the smaller size, and that's fine right now. Sudo zpool create -f zfs-alpha mirror /dev/sdb /dev/sdc On Ubuntu Server 20.04.3 I've created a 2 disk ZFS pool using the following from the Ubuntu page: Half the point of asking questions in a public sub is so that everyone can benefit from the answers-which is impossible if you go deleting everything behind yourself once you've gotten yours. If I catch anybody else deleting their question and all their comments on it immediately after getting an answer, they're getting an instant banhammer. But please don't flame people for not using your own personal One True Platform. If there's useful information about a difference in implementation or performance between OpenZFS on FreeBSD and/or Linux and/or Illumos - or even Oracle ZFS! - great. If your post or comment gets hidden, send modmail and we'll take a look. NOTE: sometimes Reddit's auto-spam system flags links it shouldn't. This isn't an issue we usually have trouble with, so let's just keep not having trouble with it. BUT, only if it's materially useful to answer a question, or offer information, in some sense other than "this will get people to give me money." It's fine to link to youtube videos, blog posts, what have you. If you think somebody's wrong, you can say that without casting aspersions or being super sarcastic. We will continue to poll regularly to ensure that it is the community itself in protest, not just the mod team.ĭon't be nasty to other people. While we are in protest mode, post approval will be on, since we'd rather not yell at innocents who didn't notice the change. In this article, we are going to discuss the ways to check if it is an SSD or HDD on Ubuntu 20. The Linux operating system can automatically detect SSD since the kernel 2.6.29 was introduced. There are different methods to verify and check if you are using an SSD or HDD. Suggested alternate topics include, Zalando Fulfillment Solutions, Zinc Formaldehyde Sulfate, and, of course, John Oliver. If so, checking the type of disk drive is quite easy on Linux. This means no filesystem discussions while the protests are in effect. In addition to pricing API access through the roof with zero warning, Huffman has made it clear that he views Redditors as voiceless resources to be exploited, not as the people who create value for the site in the first place. By community consensus determined through open voting, we are protesting the actions of Reddit CEO Steve Huffman and cohort.
