but the space_info corruption still occours. On every umount i see: [93022.166222] BTRFS: space_info 4 has 208952672256 free, is not full [93022.166224] BTRFS: space_info total=363998478336, used=155045216256, pinned=0, reserved=0, may_use=524288, readonly=65536 Greets, Stefan Am 29.09.2016 um 09:27 schrieb Stefan Priebe - Profihost AG: > Am 29.09.2016 um 09:13 schrieb Wang Xiaoguang: >>>> I found that compress sometime report ENOSPC error even in 4.8-rc8, >>>> currently >>> I cannot confirm that as i do not have anough space to test this without >>> compression ;-( But yes i've compression enabled. >> I might not get you, my poor english :) >> You mean that you only get ENOSPC error when compression is enabled? >> >> And when compression is not enabled, you do not get ENOSPC error? > > I can't tell you.
