Kevin Oberman, Network Engineer, Retired > E-mail: rkoberman@gmail.com > I'd like to understand this, because I've had some trouble trying to convert on a running machine. Specifically, I've had instances where adding labels to existing packs (using gpart modify...) and then destroying the glabel labels results in ZFS identifying pool members with their uuid instead of the label -- permanently! I've yet to have it decide to "lose" a pool member entirely, but needless to say having a uuid become the "permanent" member identifier is undesirable. I've also yet to have glabel screw me PROVIDED I put it on a slice. But most of my production machines run encrypted disks since the advent of AES-NI instruction-set enabled CPUs; so my usual pattern is this: gpart create.... gpart add -a 4k -t freebsd-zfs da[x] glabel label yourlabel da[x]p1 geli init -s 4096 -l 256 ...... /dev/label/mylabel .... zpool create ..... label/mylabel1.eli label/mylabel2.eli ..... Never had this get me in trouble as of yet. -- Karl Denninger karl@denninger.net <mailto:karl@denninger.net> /The Market Ticker/ [-- Attachment #2 --] 0 *H 01 0 + 0 *H O0K030 *H 01 0 UUS10UFlorida10U Niceville10U Cuda Systems LLC1 0UCuda Systems LLC CA1/0- *H customer-service@cudasystems.net0 130824190344Z 180823190344Z0[1 0 UUS10UFlorida10UKarl Denninger1!0 *H karl@denninger.net0"0 *H 0 bi՞] MNԿawx?`)'ҴcWgR@BlWh+ u}ApdCF JVй~FOL }EW^bچYp3K& ׂ(R lxڝ.xz?6 &nsJ +1v9 v/( kqĪp[vjcK%fϻe?iq]z lyzFO'ppdX//Lw(3 JI A*S#՟H[f|CGqJKoo y.oEuOw$ /섀$삻J9b|A P~8]D1YI<"""Y^T2iQ2 b yH)] Ƶ0y$ _N 6XqMC 9 XgώjGTP"#nˋ"Bk1 00 U 0 0 `HB0 U 0, `HB OpenSSL Generated Certificate0 U |8 ˴d[20 U #0]Af4 U3x&^"408 `HB+)https://cudasystems.net:11443/revoked.crl0 *H gBwH] j\x`( &gW32"Uf^. ^Iϱ k!DQA g{(w /)\N'[ oRW @C HO>)XrTNɘ!u`xt5(=f\-l3<@C6mnhv##1ŃbH͍_Nq aʷ?rk$^9TIa!kh,D -ct1 0001 0 UUS10UFlorida10U Niceville10U Cuda Systems LLC1 0UCuda Systems LLC CA1/0- *H customer-service@cudasystems.net0 + ;0 *H 1 *H 0 *H 1 140930130323Z0# *H 1).9! yCa @Y<w0l *H 1_0]0 `He*0 `He0 *H 0*H 0 *H @0+0 *H (0 +71001 0 UUS10UFlorida10U Niceville10U Cuda Systems LLC1 0UCuda Systems LLC CA1/0- *H customer-service@cudasystems.net0 *H 101 0 UUS10UFlorida10U Niceville10U Cuda Systems LLC1 0UCuda Systems LLC CA1/0- *H customer-service@cudasystems.net0 *H ݗܐ glQ#PcX=&VoT]QAҟ/ʬH ݔbD|[GA>L |+d{)Yj&L;(j"nL< ʋvZv>CA@V`UǍ0ߎETR6%q8Wv_ HP̶Yz,V 4b7 @C$*em)mD՟yUnV\SMJk akxˁ} W_G[+:mz+ ضuLf6ilֆz]ҰZ!GRT8E߱ZՕ ~\CbfJ R1, ah0=eRDs7'm-3uu< @rAY%X gX 0qɩM/}dʎюŏI> +Msk,8>5L,WJ3lھ76`*sQt*6NbwJ
