Have a trouble with HDD (RAID 0)

Post by t-vex » 2021/04/15 12:34:55

I have such a problem: I used to have this: There were 4 500 GB disks combined into a raid0 array (2000 GB) with an xfs file system with lvm where the Linux centos 7 operating system was installed. And everything was fine without any problems. I was happy. Then I bought a sata controller and 4 more disks of 500 GB each. But the controller turned out to be not a real raid, but a fake raid, but I combined these 4 disks into a software raid via mdadm. And I connected this software array to the lvm, and I got the full volume of all 8 disks 4 TB. But the following error appeared in my system:
#journalctl -xb
systemd-udevd[324]: inotify_add_watch(6, /dev/sdf2, 10) failed: No such file or directory
systemd-udevd[322]: inotify_add_watch(6, /dev/sdf1, 10) failed: No such file or directory

Sorry for my English.
