| fbader | Hi, I wonder if anyone can help with this. | 15:01 |
| fbader | If I have / on an LV and expanded it with another PV on EKCD DASD, how do I make sure that additional volume will be online when I reboot? I did 'chzdev -e 0201' and a 'lszdev' showed it was ON and PERS. But after reboot, it could not mount / because the 2nd PV was not online. | 15:02 |
| fbader | Is there some place where you put a list (e.g., /etc/dasd.conf, /etc/zipl.conf) of ECKD DASD that is to be online at boot? | 15:03 |
| tinoco | xnox: ^^ do we ? or we're only using dasd module parameters for chccwdev enabling dasds ? | 16:07 |
| xnox | fbader, $ chzdev -e 0201 && update-initramfs -u | 16:18 |
| xnox | chzdev -e > generates the new udev rules | 16:18 |
| xnox | update-initramfs -u rebuilds the initramfs and includes the new udev rules | 16:19 |
| xnox | fbader, i am meant to write a hook to chzdev to automatically call update-initramfs -u when needed.... | 16:19 |
| fbader | @xnox I was not aware of running "update-initramfs -u" after chzdev. I will try that and see if that resolves the issue of the device not being online at boot. Thanks! | 17:35 |
| fbader | That may also explain why when a ECKD DASD device was removed with "chzdev -d 0300" (which was online when the system was installed), that's why it kept coming back online after a reboot. | 17:38 |
| fbader | We need to do the "chzdev -e 0301" and then "update-initramfs -u" to make it permanent after a reboot. chzdev did remove the udev rule but the device was still online. | 17:39 |
| xnox | fbader, correct, because initramfs has the udev rules of whatever was on disk last time it was generated. | 18:04 |
| xnox | fbader, you can use -a to affect only active configuration, without writing udev rules on disk | 18:05 |
| xnox | e.g. $ chzdev -a -e/-d 0301 -> to enable/disable devices without writing things on disk. | 18:05 |
