Why there is no more /dev/sdb on ubuntu runners running private repo workflows ?

Hello there,

Since few days, I observe this behaviour:

• on ubuntu public runners running public-repo workflows, there still is the secondary 75 GB disk on /dev/sdb:

$ cat /etc/issue*
Ubuntu 22.04.5 LTS

$ fdisk -l
[...]
Disk /dev/sdb: 75 GiB, 80530636800 bytes, 157286400 sectors
Disk model: Virtual Disk
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0x8c7bf172

Device     Boot Start       End   Sectors Size Id Type
/dev/sdb1        2048 157284351 157282304  75G  7 HPFS/NTFS/exFAT

• While on runners running "private" workflows, that's to say public runners running private-repo workflows, there is no more this secondary disk /dev/sdb (only /dev/sda). So we now have limited disk in that case.

Do you also observe this ?
Can you put again this secondary disk for private-repo workflows ?

Cheers!

Start by comparing the fdisk -l output on Ubuntu public runners handling public-repository and private-repository workflows. Trace the runner provisioning behavior for those workflows and confirm whether the missing /dev/sdb is intentional; done means restoring the secondary disk for private workflows or documenting the expected limitation.
