#1 Updated by Sage Weil almost 12 years ago

  • Status changed from New to Duplicate

this is the signal handler thing

#2 Updated by John Spray about 7 years ago

  • Project changed from Ceph to CephFS
  • Category deleted (1)

Bulk updating project=ceph category=mds bugs so that I can remove the MDS category from the Ceph project to avoid confusion.
