"WARNING: Detected error segment type does not match expected type striped for /_tdata"
When detecting an error'ed _tdata volume, lvm warns that the segment type does not match expected type 'striped', but the _tdata would never be a 'striped' type and would always be 'linear'. Sure the -tpool volume may use striping with the data and meta, but it still lists a type of 'thin-pool' in that case.
- An actual striped table:
thinpool_sanity-my_stripe: 0 221184 striped 3 128 8:0 58843136 8:16 8192 8:32 8192
- Various thinpool tables:
thinpool_sanity-thin_pool-tpool: 0 58720256 thin-pool 253:2 253:3 128 137625 0
thinpool_sanity-thin_pool_tmeta: 0 57344 linear 8:0 8192
thinpool_sanity-thin_pool_tdata: 0 58720256 linear 8:0 65536
