Well I have already removed device physically and the pool continues to work despite yelling about missing log device. I already tried booting from flash drive and importing/exporting pool - this doesn't work. I also tried to replace this log device with another one. Replacing works and I can remove old device but the new one will now be unkillable. Am I right that working without external log device is almost the same as working with disabled ZIL? -- Sphinx of black quartz judge my vow.
