The resize operation will suspend & resume swap device (by reload dm table). After suspended swap device, lvmetad will be in UN status for waiting swapin pages from suspended swap dev. lvmetad will hung, then lvresize will fail to conection to lvmetad. then the resize operation will fail, lvresize leaves suspended swap, the logic dead lock is happending. Hi It seems there is something wrong elsewhere. There should be no contact to lvmetad while ANY devices are in suspend state. Maybe something got reshuffled into wrong place. Can you please provide 'lvextend -vvvvv' when it hangs ?
