I have an older i386 system with an 8TB filesystem on it, roughly 40 millio= n inodes.=0A=0AIt appears that this is impossible to fsck - I have nudged u= p maxdsiz all the way to:=0A=0Akern.maxdsiz=3D"3072000000"=0A=0A=0Aand it's= not enough. =A0Any larger values cause the system to become unbootable.=0A= =0ASo, my plan is to boot 8.x amd64 FIXIT, and run fsck from the fixit envi= ronment.=0A=0AThe issues I foresee are:=0A=0A1. Do I need to specify a maxd= siz in the 8.x fixit environment, or does this all just autoscale=0Athese d= ays ? =A0I'm hoping my process doesn't grow past 3.5 GB, but do I need to b= urn a=0Acustom fixit to do that ? =A0Or can I drop into the boot loader of = FIXIT and set a custom load=0Avalue ?=0A=0AOr perhaps I don't care at all a= nd maxdsiz will just auto-scale to however large the fsck gets ?=0A=0A=0A2.= There is only 4 GB of physical in the system ... if I could grow to 3.072 = GB process size in=0Ai386, then all else being equal, I should be able to g= row to 3.5 in 8.x FIXIT, right ?=0A=0A=0A3. If I get larger than 4 GB in am= d64, with a 4GB physical memory, I can always swap, right ?=0ABut where wou= ld I swap to ? =A0Maybe I could mount my /var (which is clean, and is 4 GB = in size)=0Aand swap to there ?=0A=0ACan I specify a file-backed swapfile in= FIXIT ?=0A=0A=0AAnything else I am missing ?=0A=0A=0AThanks.
