Hi All,
Am I correct in thinking that in latest kernels, now that krbd is supported via blk-mq, the maximum queue depth is now 128 and cannot be adjusted https://github.com/torvalds/linux/blob/master/drivers/block/rbd.c 3753: rbd_dev->tag_set.queue_depth = BLKDEV_MAX_RQ; blkdev.h 42: #define BLKDEV_MAX_RQ 128 This potentially seems a bit low for some use cases if it can't be adjusted.
