LVM volume name

[Martin Brachtl]

Are there any constraints on the length of the volume name? I guess, the constraints are the same as in the case of the filename. Am I wrong?

That's all the man page says:

"where lv_name is a simple file name, not a path name"

well, I read that, but this is not "a proof" that there are no other constraints.

I would keep not get crazy with the naming. Remember if something goes wrong your gonna have to type these puppies.

Keep it somewhat short and it will keep the `bdf` output on 1 line.

Get longer vg_ & lv_ names and the `bdf` display has too use multiple lines.

I am asking because the author of application suggested pretty long names. Shall I say to him, silly long names, but it will work, or, will not.

It will work, but there is a point where readability clashes with useability, especially if you are the system administrator.

Hi,

I wouldn't use very long names, they are not pratical for administration, some tools like Glance, MeasureWare, OVO will truncate those names.

Enjoy :)

What does the author mean by "pretty long names" ?
"BeautifulDreamer001" ? :-)

lvol2 is long enough for me. But, it's probably not all that pretty. :-)

[Rick Garland]

The long names will work.

Do keep in mind the balance act between readability and useability

Tell the developer that the system administration policies do not allow for fancy names. After all, where will those volume groups be used? As parameters and/or answers to questions in the application? Or just some names in a config file? VG's are sysadmin symbols. Long VG names will create a *LOT* of sysadmin pain in the future as apps (like Glance and OV) and tools like bdf try to work around the long names. It won't be pretty...

[Martin Brachtl]

"Pretty long" is something like this:

/dev/vgxx/cust_scoring1_db12_arch_log_w_1

I would not choose anything like that, because of all reasons you mentioned. And I was not sure, if this is also technically possible. It seems, it is.

BTW thank you all for the responses.
