| Summary | 0016942: Installation fails on pre-partitioned software RAID | ||||
| Description | I have a server that has its OS on a RAID 1 of two SSDs. I wanted to install CentOS as the new operating system, while keeping the old one available, so I shrunk the original filesystem, repartitioned the SSDs and created new RAIDs on the partitions, v0.9 metadata for the OS to be on the safe side for booting. The old OS boots and works just fine. Disk layout for both SSDs is like follows: # fdisk -l /dev/sdi Disk /dev/sdi: 300.1 GB, 300069052416 bytes 255 heads, 63 sectors/track, 36481 cylinders, total 586072368 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00008b43 Device Boot Start End Blocks Id System /dev/sdi1 2048 4196351 2097152 82 Linux swap / Solaris /dev/sdi2 * 4196352 134219775 65011712 fd Linux raid autodetect /dev/sdi3 134219776 264243199 65011712 fd Linux raid autodetect /dev/sdi4 264243200 586072367 160914584 fd Linux raid autodetect The first raid partition is a RAID1 with the old OS: # mdadm -D /dev/md1 /dev/md1: Version : 0.90 Creation Time : Fri Dec 13 17:58:06 2019 Raid Level : raid1 Array Size : 65011648 (62.00 GiB 66.57 GB) Used Dev Size : 65011648 (62.00 GiB 66.57 GB) Raid Devices : 2 Total Devices : 2 Preferred Minor : 1 Persistence : Superblock is persistent Update Time : Thu Jan 9 15:14:56 2020 State : clean Active Devices : 2 Working Devices : 2 Failed Devices : 0 Spare Devices : 0 UUID : f2d83e21:53b00d3b:04894333:532a878b Events : 0.1 Number Major Minor RaidDevice State 0 8 130 0 active sync /dev/sdi2 1 8 146 1 active sync /dev/sdj2 I created new RAIDs on the new partitions (abbreviated): # mdadm -D /dev/md2 /dev/md2: Version : 0.90 Creation Time : Thu Jan 9 15:36:39 2020 Raid Level : raid1 Array Size : 65011648 (62.00 GiB 66.57 GB) [...] UUID : 15d9716d:e9e47889:a6b0c1bc:0e02d2b0 (local to host zuse2) Events : 0.11 Number Major Minor RaidDevice State 0 8 131 0 active sync /dev/sdi3 1 8 147 1 active sync /dev/sdj3 # mdadm -D /dev/md3 (this one with v1.2 metadata, because it doesn't need to be bootable): /dev/md3: Version : 1.2 Creation Time : Thu Jan 9 15:37:11 2020 Raid Level : raid1 Array Size : 160783424 (153.34 GiB 164.64 GB) [...] Name : zuse2:sys (local to host zuse2) UUID : 46a71480:7534c6bf:943a2006:983ac7bd Events : 1 Number Major Minor RaidDevice State 0 8 132 0 active sync /dev/sdi4 1 8 148 1 active sync /dev/sdj4 I tried to install CentOS on sdi3+sdj3, with and without pre-creating a raid there, with sdi1+sdj1 reserved as swap (not RAID!) and sdi4+sdj4 to be assembled as a system data RAID 1 (OS-independent). Installation always fails after it booted into X. All I see is a black screen with a mouse pointer, when booting without the SSDs attached I got into the graphical user interface, so graphics itself is working. Installing with textual interface doesn't do any good either. When switching back to VT1, on the text console it states the following error: ERROR:pugi-argument.c:1006:_pygi_argument_to_object: code should not be reached anaconda.log logs the following error (all log files attached): [...] File "/usr/lib/python3.6/site-packages/blivet/populator/populator.py", line 264, in handle_device device = helper_class(self, info).run() File "/usr/lib/python3.6/site-packages/blivet/populator/helpers/partition.py", line 112, in run self._devicetree._add_device(device) File "/usr/lib/python3.6/site-packages/blivet/threads.py", line 53, in run_with_lock return m(*args, **kwargs) File "/usr/lib/python3.6/site-packages/blivet/devicetree.py", line 158, in _add_device raise ValueError("device is already in tree") ValueError: device is already in tree I checked the uuids of the parititions, and indeed the (potential) RAIDs have identical uuids - but that seems to be normal (according to what I read): # blkid /dev/sdi? /dev/sdj? /dev/sdi1: UUID="42e567fd-92e2-4245-b143-6f6fead66003" TYPE="swap" /dev/sdi2: UUID="f2d83e21-53b0-0d3b-0489-4333532a878b" TYPE="linux_raid_member" /dev/sdi3: UUID="15d9716d-e9e4-7889-a6b0-c1bc0e02d2b0" TYPE="linux_raid_member" /dev/sdi4: UUID="46a71480-7534-c6bf-943a-2006983ac7bd" UUID_SUB="4264cf23-e3f9-99b9-7978-478f5a7c18cf" LABEL="zuse2:sys" TYPE="linux_raid_member" /dev/sdj1: UUID="823a2345-5b62-4f28-8618-e1184e1c4032" TYPE="swap" /dev/sdj2: UUID="f2d83e21-53b0-0d3b-0489-4333532a878b" TYPE="linux_raid_member" /dev/sdj3: UUID="15d9716d-e9e4-7889-a6b0-c1bc0e02d2b0" TYPE="linux_raid_member" /dev/sdj4: UUID="46a71480-7534-c6bf-943a-2006983ac7bd" UUID_SUB="99872eb9-362f-38bb-6d06-71c0b9d20480" LABEL="zuse2:sys" TYPE="linux_raid_member" What's happening here, and more importantly - how do I install CentOS on this system? What additional information would be necessary to debug the problem? | ||||
| Steps To Reproduce | On my machine: trivial, try to install. On others: unknown; probably try to install on a prepartitioned software RAID 1 system. | ||||
| Additional Information | For completeness, I used the network install medium; will try to use 8.1.1911 next. | ||||
