>From Thomas Bruecker, Switzerland. Dear DM-Developers, I have questions about swapping to device-mapper targets: Question 1: Provided that "sda1" and "sdb1" are two devices, to which I may swap without any problems, e.g. with the entries in "/etc/fstab": " /dev/sda1 swap swap defaults 0 0 /dev/sdb1 swap swap defaults 0 0 ". May I swap also to the mirror target "test_raid" created by the statement ' dmsetup create test_raid \ --table "0 8388608 mirror core 2 8388608 sync \ 2 /dev/sda1 0 /dev/sdb1 0 " ' without any problems (e.g. deadlocks)? (The command above completes successfully and therefore there is enough space on "sda1" and "sdb1" to create the target.) Question 2: Provided the table entry form for a mirror target is: ' ... --table " $START $LENGTH mirror \ $LOG_TYPE $NumLOGARGS $LOGARG1 ... $LOGARGm \ $NumDEVS $DEVICE1 $OFFSET1 ... $DEVICEn $OFFSETn " ' Does your answer to question 1 only hold for the parameters I specified in question 1 or for all legal parameters $... (of the above table entry form)? I have searched your site "http://www.redhat.com/archives/dm-devel/" by google for answers to my above questions, but I have not found any answer to them there. So I would be happy to get an answer from you. Sincerely Thomas Bruecker -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
