Indeed: we were seriously bitten by this one, taking three Solaris 10
fileservers down for about a week until the problem was diagnosed by Sun
Service and an IDR provided. Unfortunately, this issue (seriously
fragmented pools or pools beyond ca. 90% full cause file servers to grind
to a halt) were only announced/acknowledged publicly after our incident,
although the problem seems to have been reported almost two years ago.
While a fix has been integrated into snv_114, there's still no patch for
S10, only various IDRs.
It's unclear what the state of the related CR 4854312 (need to defragment
storage pool, submitted in 2003!) is. I suppose this might be dealt with
by the vdev removal code, but overall it's scary that dealing with such
fundamental issues takes so long.
