====== Avance III 400 MHz SB - Altres tasques post-configuració del TopSpin ======

Aquesta pàgina conté les tasques posteriors a la instal·lació de les dues versions 3.6.3 i 3.6.4 del Topspin. Per exemple: organitzar les carpetes creades, eliminar les carpetes redundants o innecessàries, organitzar les carpetes de dades, etc. 

===== Carpetes amb versions anteriors del TopSpin =====

  * Moc les carpetes ''/opt/topsin3.6.3/conf/instr/topspin3.5pl6'' i ''/opt/topsin3.6.3/conf/instr/topspin3.6.1'' dins ''/opt/topspin3.6.4/conf/instr''.
  * Moc la carpeta ''/opt/topsin3.6.3/'' dins ''/opt/topspin3.6.4/conf/instr''
  * Elimino de ''/opt/topspin3.6.4/conf/instr/'' les carpetes i fitxers innecessaris de les instal·lacions anteriors, entre altres: ''examdata'', ''guide'', ''jython'', ''prog/docu'', etc.

L'espai final ocupat pels fitxers de configuració de les anteriors instal·lacions és:

===== Discos durs HDD =====

Aquests són els discos durs HDD procedents d'altres ordinadors i instal·lats al nou ordinador.

<WRAP important>
SMART indica que aquest disc ha estat en funcionament 4 anys i 3 mesos, però que no té cap problema. En qualsevol cas, **aquest disc dur no es farà servir al nou ordinador,** i **caldrà transferir el seu contingut al nou disc dur HDD.**

Després de comprovar que les dades de RMN ja es van transferir al servidor de dades, i de transferir algunes carpetes que podrien tenir un interès //històric,// esborro les particions al disc. Llavors creo dues particions de 500 GB cadascuna sense sistema de fitxers i començo a configurar-les per LVM,

       this file system.  For more details see restorecon(8) and mount(8).

Llavors, per cadascuna d'aquestes carpetes //actives//, moc les carpetes de dades més recents de ''archive'' a ''current''. Ho faig a mà amb l'ajut del programa ''Mindight Commander'' després de [[https://unix.stackexchange.com/questions/354215/change-sort-order-with-shortcuts-in-midnight-commander | definir unes dreceres de teclat]] per fer la tasca una mica menys feixuga.

  * Quick search: <key>ctrl-s</key>
  * Sort by name: <key>alt-#</key>
  * Sort by MTime: <key>alt-&</key>

===== IN PROGRESS - Compartir les carpetes de dades =====

<WRAP todo>
  * muntar la carpeta compartida al servidor de dades i muntar per separar ''current'' i ''archive''.
</WRAP>

==== Exportar les carpetes de dades ====

Afegeixo les següents línies per compartir la carpeta de dades i la carpeta ''~topspin/exp/stan/nmr/list'' amb el servidor de dades,

<file>
# SERMN - EXPORTED FOLDERS

# Export NMR data folder to SeRMN data server
# Because of SELinux, the data folder cannot be inside a home folder
/opt/nmrdata sermn.uab.cat(ro,sync,no_subtree_check,root_squash,all_squash,insecure)

# Export TopSpin 3.6.4 lists folder to SeRMN data server
/opt/topspin3.6.4/exp/stan/nmr/lists sermn.uab.cat(ro,sync,no_subtree_check,root_squash,all_squash,insecure)
</file>

i exporto les carpetes

<file>
# exportfs -v -a
exporting sermn.uab.cat:/opt/topspin3.6.4/exp/stan/nmr/lists
exporting sermn.uab.cat:/opt/nmrdata
exporting spect:/usr/diskless/clients/spect
exporting spect:/usr/diskless/dl_usr

# exportfs -v
/usr/diskless/dl_usr
                spect(sync,wdelay,hide,no_subtree_check,sec=sys,ro,secure,root_squash,no_all_squash)
/usr/diskless/clients/spect
                spect(sync,wdelay,hide,no_subtree_check,sec=sys,rw,secure,no_root_squash,no_all_squash)
/opt/nmrdata    sermn.uab.cat(sync,wdelay,hide,no_subtree_check,sec=sys,ro,insecure,root_squash,all_squash)
/opt/topspin3.6.4/exp/stan/nmr/lists
                sermn.uab.cat(sync,wdelay,hide,no_subtree_check,sec=sys,ro,insecure,root_squash,all_squash)
</file>

==== Muntar les carpetes de dades ====

Edito el fitxer ''/etc/fstab'' al servidor per actualitzar la informació sobre les carpetes exportades per l'espectròmetre,

i la resposta m'indica que hi ha comunicació entre els dos ordinadors, però que no es pot accedir al servei ''portmapper'' del servidor de NFS, potser perquè la configuració del firewall a l'espectròmetre ho impedeix. L'informe de la comanda ''traceroute'' indica el mateix, pot accedir a l'ordinador i pot mesurar el temps de resposta (per exemple, 2.026 ms), però no pot accedir als ports que fa servir per comprovar l'accés l'ordinador i per això surt ''!X'' a l'informe.

Comprovo la configuració del tallafocs a l'espectròmetre,

<file>

[root@cie-54-214 sermnadmin]# firewall-cmd --list-services

</file>

i afegeixo els serveis relacionats amb NFS que manquen,

<file>
[root@cie-54-214 sermnadmin]# firewall-cmd --permanent --zone=public --add-service=mountd
success

[root@cie-54-214 sermnadmin]# firewall-cmd --permanent --zone=public --add-service=nfs
success

[root@cie-54-214 sermnadmin]# firewall-cmd --permanent --zone=public --add-service=rpc-bind
success

[root@cie-54-214 sermnadmin]# firewall-cmd --reload
success

[root@cie-54-214 sermnadmin]# firewall-cmd --zone=public --list-services                                                                               
dhcpv6-client mountd nfs rpc-bind ssh
</file>

Torno a comprovar si el servidor de dades ja pot accedir al servidor NFS a l'espectròmetre,

<file>
root@sermnserver:/etc# rpcinfo -p cie-54-214.uab.cat
   program vers proto   port  service

    100026    1   udp    766  bootparam
</file>

i com que ara té accés, provo a muntar la carpeta de dades i aquest cop funciona, 

<file>

===== Configuració del TopSpin =====

==== Data Browser ====

Copio el fitxer ''browsedir2_Local.prop'' de l'Avance Neo 400 MHz dins la carpeta ''/home/sermnuab/.topspin/prop'' i l'edito per canviar la ubicació de les carpetes de dades (''/opt/nmrdata/current/'') i eliminar els enllaços específics de l'altre espectròmetre. El resultat és,

Copio el fitxer a ''/home/sermnadmin/.topspin/prop'' perquè tots dos comptes vegin les mateixes carpetes.

==== PENDENT - Error setting parameter "LIFTMODE" ====

<WRAP todo>
  * He enviat a Bruker aquest error i estic a l'espera de la seva resposta.
  * La resposta és que cal actualitzar el firmware de la placa ELCB.
  * Actualitzo el firmware però el missatge d'error no desapareix.
  * Envio la nova informacíó amb Bruker.
  * La nova resposta és que afecta a tots els equips amb BVT en comptes de BSVT, i que estan treballant en una solució.

Sortosament, aquest error no sembla afectar al funcionament del TopSpin.

Segons Bruker, aquest error es resol actualitzant el firmware de la placa ELCBñ. La versió actualment instal·lada és,

i a la pàgina "BSMS Service Web - Setup" ho confirma,

Clico a l'enllaç ''Load new firmware'' i em descarrego la darrera versió disponible ''elcb_firmware_210212.gz
'' del [[ftp://ftp.bruker.ch/NMR/download/servtools/firmware/elcb/ | servidor FTP de Bruker,]] i la instal·lo. Un cop finalitzada la instal·ació del nou firmware. torno a comprovar la versió instal·lada,

^ Unit                 ^ Version  ^ Date         ^
| ELCB Firmware        |   210212 |  Feb 12 2021 |
| Bootloader Firmware  |       CB |  Feb 19 2007 |

i a la pàgina "BSMS Service Web - Setup" la columna ''Status'' marca que els firmwares de totes les plaques són correctes.

Llavors reinicio TopSpin per comprovar si ja no apareix l'error i malauradament **l'error no ha desaparegut.**
