#1 Updated by Neha Ojha 5 months ago

Hi Igor, this seems new in master. So far just one occurrence but I am assigning this to you for your thoughts.

#2 Updated by Igor Fedotov 5 months ago

  • Status changed from New to Triaged

Given the following line I presume we're just out of space for WAL volume (which has got 512MB only):

-1 bluefs _allocate_without_fallback unable to allocate 0x500000 on bdev 0, allocator name bluefs-wal, allocator type hybrid, capacity 0x20000000, block size 0x100000, free 0xff000, fragmentation 0, allocated 0x0

Perhaps one should simply increase WAL size for test suit(s).
