However an initial experiment with t= his value appears to diverge from assumptions I had made. My context is related to TLER smartctl -l scterc,${TIMEOUT_SEC}0,${TIMEOUT_SEC}0 /dev/sdX I have a software RAID (ZFS in this case) which isn't interacting the way it expects with underlying hardware. I was hoping to find a manual that might explain how the block device tunable fields such as 'timeout' are intended = to be utilized and tuned. I didn't see anything obvious in search of text and 'reStructuredText' files with the obvious keyword: https://github.com/torvalds/linux/search?l=3DText&p=3D6&q=3Dtimeout https://github.com/torvalds/linux/search?l=3DreStructuredText&p=3D16&q=3Dti= meout --=20 You may reply to this email to add a comment.
