What’s your actual question? Feel free to use complete sentences and paragraphs to explain.

Yes - you can disable anything by taking a sledgehammer to it.

Unfortunately that is the only sensible answer I can give that fits the non-sensical question. Here are my questions about your questions:

  • “Disable this info? Possible?” Are you asking how we can disable TrueNAS from showing this info i.e. prevent it from being shown in the UI?

  • Or are you asking what the “error” is for and can you disable it for this specific error? In which case my guess (in the absence of any more data) is that it is indicating that you have a pool of mixed sized disks, but it could be telling you that you have a degraded pool (one disk broken) or an unavailable pool (2 or more disks broken) or indeed something else entirely.

    But if this is what you are asking, then “no” you cannot disable the Mixed Capacity error flag, and “yes” you can make it go away (by using disks of all the same size).

That said, my experience here is that people who used mixed disks often compromise on other much more important aspects of their configuration, in which case it is possible you have much more serious issues that haven’t YET come to bite you.

Please run the following commands in a command shell to give us more diagnostic information (and post the output from each command in a separate </> box):

  • lsblk -bo NAME,MODEL,ROTA,PTTYPE,TYPE,START,SIZE,PARTTYPENAME,PARTUUID
  • lspci
  • sudo sas2flash -list
  • sudo sas3flash -list
  • sudo zpool status -v

Thanks.

AS I SAID On web ui/Storage/Topology

Data VDEVs
PRT
The info is about different disk capacities , when i hover on the orange circle.

See clear now ?

The status command show no error.

Thanks

Not at all. What is it you’re trying to remove, and why? The point of that widget is to show you the layout of your pool, so if you’re asking if that can be removed, no, it can’t. If you’re asking that the “mixed capacity” be removed, again, no it can’t, nor should it.

Complete sentences and paragraphs, please.

Ok you both answered my question , i have mixed capacities on that vdev , but its funny that we can disable critical errors on system Alert settings and not this, that imo is cosmetic, offcourse i know i have some lba’s larger on 1 disk.
I just dont want to pass a shock when i see it next time. I am refering only to the orange exclamation mark and not the 1 x RAIDZ1 | 5 wide | Mixed Capacity info.
But never mind its there to remind me to take my pills before I see it.

Thanks both

@drigo I think we all appreciate that English is not your native language, but even making all reasonable allowances for that you did not really help yourself here.

When asking a question, 1) Your title needs to give a basic explanation of the issue i.e. “mixed disk sizes - can I turn off warning button in UI?”; and 2) you need to give details when you first ask i.e. screen shots, cli command output etc.

Even your later screenshot did NOT include the tooltip from the orange :exclamation: button.

That said, I think your request is reasonable. Since mixed disk sizes is a permanent state, I don’t think it should have a permanent warning badge like this because you will not then see a more important warning (like corrupt files).

Thank you for your reply, and sorry
I will try to give more information on the question next time, but I was not so wrong you got it from start, both of you.

I was thinking exactly that you wrote as offcourse you can’t have same disks after some years as they become discontinued.
“That said, I think your request is reasonable. Since mixed disk sizes is a permanent state, I don’t think it should have a permanent warning badge like this because you will not then see a more important warning (like corrupt files).”

Thanks again,

Actually, I think the most appropriate UI is a warning when you create a vDev or add a device to a vDev (additional mirror or RAID expansion):

  1. Warning: You are creating a vDev using disks of different sizes. The smallest of the disk sizes will be used for all disks, and the remaining space will be unused.

  2. Error: You are attempting to add a device to the vDev that is smaller than the existing vDev usage, and this is not allowed. (This error probably already exists.)

  3. Warning: You are adding a disk to an existing vDev that is larger than the existing space used by this vDev. The remaining space on this disk will be unused.

Once the user accepts the warnings, there is little point in continuing to flag this except to use the phrase “Mixed Capacity” as at present. If you want to provide a further explanation then a tooltip on the phrase “Mixed Capacity” would be the place for it.
