Found xfs filesystem 6973030400 kB data area apparently used 6972817564 kB left usable by current configuration

Device size would be truncated, which would corrupt data and result in 'access beyond end of device' errors. You need to either

  • use external meta data (recommended)
  • shrink that filesystem first
  • zero out the device (destroy the filesystem) Operation refused.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
