So if you have enough uncommitted metadata, that check will be triggered and suddenly returns 0 available space, even 1 sec early you still get tons of available space.
With « uncommitted metadata » do you mean that this situation is only temporary and should end once all transactions are commited to disk ?
Because in the one disk on which I observe this (and which passes a full btrfs check with bells and whistles) it still shows 0% free after 2 days and several unmounts / remounts...
Furthermore I've conected it to machines using 5.3 and even 4.15 kernels, and they *ALL* state that the free disk space is zero - even though I can understand if « That check is from 2015 ».
That still seems to boild down to : Once I got this error it seems I cannot step out of it using any reasonably recent kernel.
So I may have either to patch my kernel or wait for the patch to reach #Arch kernels... and hope it actually fixes it.
(I have to admit that I haven't yet fully understood the technical aspects of this overcommit story...)
I'm also worried that on my machines that does NOT show this problem on their own main filesystems, this could happen anytime soon ?
Thanks anyway very much for your help. Kind regards. ॐ -- Swâmi Petaramesh <swami@xxxxxxxxxxxxxx> PGP 9076E32E
