Re: xfs_repair on filesystem stuck in "rebuild AG headers and trees"?

Hi,
thanks for the tip.
I tried xfsprogs version  6.0.0 from newer ubuntu and it seems it fixed the filesystem (or at least did not spiral into loop :)
Meantime, i have created new filesystem, so i will keep this one until data do replicate to new filesystem

Thanks,
Libor

Both your kernel and xfsprogs are older versions from your distro.

I would report this bug to your distro, or try upstream versions to see if
the problem has been resolved.
