I am attempting to share a drive between two VMs. When I provision a drive as Eagerly Zeroed without turning sharing on, after the drive formats, ESXi displays it as Lazily Zeroed. It took several hours to format.
I was able to get around this by turning sharing on when creating the drive. Now it shows correctly on the machine it was initially set up on:
However, when I try to set it up on another machine, the same disk appears as lazily zeroed:
I executed a mkfstools -D on the disk to verify the state, and this is the result:
Lock [type 10c00001 offset 112467968 v 44, hb offset 3440640
gen 85, mode 0, owner 00000000-00000000-0000-000000000000 mtime 659
num 0 gblnum 0 gblgen 0 gblbrk 0]
Addr <4, 3, 17>, gen 28, links 1, type reg, flags 0, uid 0, gid 0, mode 600
len 472, nb 0 tbz 0, cow 0, newSinceEpoch 0, zla 4305, bs 65536
tbz 0 should mean that the disk is eager thick, but it is still not registering correctly.
ESXi 6.5.0 Update 2 (Build 8294253). Updating limited due to compatibility with the LSI raid controller's management package.
